Our current study aimed to examine the association between serum albumin and new-onset hyperuricemia among participants with hypertension, and to explore the potential factors that might modify the association. Methods: This study included 10,617 hypertensive patients with normal uric acid (UA) concentrations (<357 μmol/L) at baseline from the UA Substudy of the China Stroke Primary Prevention Trial (CSPPT). The primary study outcome was new-onset hyperuricemia, which was defined as a UA concentration at the exit visit ≥357 μmol/L in women or ≥417 μmol/L in men. Results: During the median follow-up duration of 4.4 years, 1664 (15.7%) new-onset hyperuricemia cases were documented. Overall, there was a significantly inverse relation of serum albumin with risk of new-onset hyperuricemia (per SD increment; odds ratio [OR], 0.74; 95% confidence interval [CI]: 0.70, 0.79). Consistently, when serum albumin was evaluated as quartiles, compared with participants in the first quartile (<46.1 g/L), a significantly lower risk of new-onset hyperuricemia was observed among those in the fourth quartile (≥51.7 g/L; OR, 0.55; 95% CI: 0.47, 0.65). The findings were consistent among participants with different baseline characteristics. Conclusions: There was a significantly inverse association between serum albumin and risk of new-onset hyperuricemia in adults with hypertension.","PeriodicalId":74488,"journal":{"name":"Precision nutrition","volume":"2 1","pages":"e00027"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44714805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A total of 34,878 oncology patients admitted to hospitals from 2014 to 2021 were enrolled (INSCOC study). Nutritional Risk Screening 2002 (NRS 2002) and Patient-Generated Subjective Global Assessment (PG-SGA) were used to screen patients for nutritional risk and assess their nutritional status, and nutritional therapy data was gathered. Results: From 2014 to 2021, there was an overall decreasing trend in the prevalence of nutritional risk and malnutrition among oncology inpatients (χ2trend = 108.154, P < 0.001; χ2trend = 70.230, P < 0.001), with malnutrition in patients falling from 68.1% in 2014–2015 to 57.2% in 2020–2021, while malnutrition rates in patients with cervical cancer and malignant lymphoma are gradually increasing. The overall rate of total nutritional therapy for patients is on the rise (χ2trend = 67.548, P < 0.001), increasing from 39.4% (2014–2015) to 44.7% (2020–2021). A trend of rising and then falling rate of parenteral nutrition therapy was observed in patients, whereas the rate of enteral nutrition therapy grew annually (P for trend < 0.001). Nutritional therapy rates for malnourished patients are on an increasing trend, a slight increase, however, remains for well-nourished patients (P for trend < 0.001). Moreover, the prevalence in elderly oncology patients (≥60 years) also showed a downward trend in both nutritional risk and malnutrition (χ2trend = 38.897, P < 0.001; χ2trend = 75.616, P < 0.001), but malnutrition rates were higher in elderly patients than in individuals under 60 years at different years (P < 0.05). Conclusions: The great majority of patients with malignancy have a significantly decreased prevalence of nutritional risk or malnutrition from 2014 to 2021, and the rate of nutritional therapy is on the rise. However, the nutritional status of individuals with cervical cancer and malignant lymphoma remains poor. The problem of malnutrition remains prominent in elderly patients despite improvements in their nutritional status.","PeriodicalId":74488,"journal":{"name":"Precision nutrition","volume":"2 1","pages":"e00028"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44984750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pterostilbene, a resveratrol dimethyl ether analogue, has been demonstrated to have anti-obesity effects. However, studies on the mechanisms by which pterostilbene exert anti-obesity effect are still inadequate. As such, the current study tests the hypothesis that pterostilbene administration induces browning of white adipose, thus controlling body weight gain. Method: The effects of pterostilbene administration on white adipocytes browning in inguinal white adipose tissue (iWAT) of rats and 3T3-L1 adipocytes as well as their underlying mechanisms were investigated in the current study. Results: The administration of pterostilbene for 8 weeks reduced rats’ body weight gain and iWAT index. Furthermore, pterostilbene increased the content of mitochondria and the expression of brown and beige adipocyte markers such as uncoupling protein 1 (UCP1), PR domain-containing 16 (PRDM16), and transmembrane protein 26 (TMEM26) in iWAT. Pterostilbene treatment also activated AMP-activated protein kinase (AMPK) and increased expression of peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1α) in iWAT. In agreement with the in vivo findings, the in vitro results showed that 1 μM pterostilbene treatment also activated AMPK and increased PGC-1α expression, and stimulated formation of brown-like adipocytes as evidenced by the increased mitochondria content and expression of brown and beige adipocytes markers in 3T3-L1 adipocytes. However, those positive effects of pterostilbene on 3T3-L1 adipocytes were significantly inhibited by pretreatment with an AMPK inhibitor (compound C) or PGC-1α siRNA. Conclusion: These findings suggest that pterostilbene exerts body weight gain-lowering effect by inducing white adipocytes browning via the AMPK/PGC-1α pathway.","PeriodicalId":74488,"journal":{"name":"Precision nutrition","volume":"2 1","pages":"e00032"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43788686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: The current study aims to discover how L-arginine induces the cell apoptosis in gastric carcinoma. Methods: The cytotoxicity and apoptosis rate of SGC-7901 cells incubated in the RPMI-1640 medium supplemented with L-arginine were detected by CCK8 and flow cytometry. High-throughput RNA-sequencing was performed to search for differentially expressed genes (DEGs).

Nutrition and lifestyle are major contributors. Currently, there is a paucity of strong evidence to guide optimal intake of macronutrients and micronutrients for primordial, primary, and secondary prevention of chronic diseases among diverse populations and across life stages in China. Evidence is also lacking on the KAP (Knowledge, Attitude, and Practice) in Chinese populations to inform effective behavior interventions. The China Precision Nutrition and Health-KAP Real World Study (CPN-KAPS) intends to establish a cohort and conduct research in real-world settings to improve KAP and advance precision nutrition. Methods: The CPN-KAPS is a long-term, multicenter, prospective, observational, real-world study that will enroll at least a million adults who meet the inclusion criteria. Each participant will be expected to attend at least 5 follow-up visits (once a year). The primary endpoints include nutritional status and the occurrence, progression, and prognosis of numerous chronic diseases such as cardiovascular and cerebrovascular disease, tumors, chronic kidney disease, Alzheimer’s disease, digestive system diseases, diabetes, mortality, and results of the health KAP survey. Secondary endpoints include malnutrition and changes in various chronic disease-related biomarkers and pharmacoeconomic indicators. Results: The CPN-KAPS is still in a formative stage, but we anticipate this study will establish a rich database and biorepository. These resources will create enormous opportunities for scientific discoveries and clinical public health translation.

Elevated plasma total homocysteine (tHcy) coupled with hypertension can synergistically increase the risk for CVD and is highly prevalent in the Chinese population. The China Stroke Primary Prevention Trial has shown the efficacy of taking a daily enalapril-FA tablet in treating hypertension and HHcy. However, a substantial portion of patients cannot tolerate enalapril, an angiotensin-converting enzyme inhibitor (ACEI). The Precision Amlodipine-folic acid Trial to lower tHcy (ClinicalTrials.gov Identifier: NCT01956786) aimed to evaluate whether amlodipine combined with folic acid treatment is more efficacious than amlodipine alone in lowering plasma tHcy and blood pressure (BP) among Chinese patients with hypertension with HHcy and intolerance to ACEI. Methods: This was a multicentered, randomized, double-blind, parallel-controlled clinical trial conducted from December 19, 2013, to March 6, 2014, in 4 study centers across China (Shanghai, Nanchang, Xuzhou, and Anqing). Eligible participants who had mild to moderate hypertension were men and women aged 18 to 75 years, hyperhomocysteinemia and intolerant to ACEI. Eligible patients were randomly assigned in a 1:1:1 ratio to receive either an amlodipine 5 mg and FA 0.4 mg tablet daily (A group); or an amlodipine 5 mg and FA 0.8 mg tablet daily (B group); or an amlodipine 5 mg tablet daily (C group, control group) for a total of 8 weeks. The primary endpoints were tHcy-lowering and BP assessed at 2, 4, 6, and 8 weeks. Planned analyses included intent to treat and per protocol set, and multivariable logistic and linear regression models were used to evaluate the efficacy of amlodipine combined with FA in reducing tHcy and BP. Results: A total of 505 participants were enrolled in the screening period; of those, 458 entered the run-in period, and of those, 360 eligible participants were randomized to one of the 3 treatment groups. Overall, 31.3% of participants were male (n = 110), with a mean age of 63.2 (SD: 6.2) years. The randomization was successful as demonstrated by the well-balanced distribution of baseline characteristics across the 3 groups.
