Dietary choline intake and colorectal cancer: a cross-sectional study of 2005-2018 NHANES cycles.

Background: It remains unclear if choline intake is associated with colorectal cancer. Therefore, we examined data from the National Health and Nutrition Examination Survey (NHANES). Methods: This cross-sectional study included 32,222 U.S. adults in the 2005-2018 NHANE cycles, among whom 227 reported colorectal cancer. Dietary choline was derived from 24-h recalls. Logistic regression estimated odds of colorectal cancer across increasing intake levels, adjusting for potential confounders. Results: After adjusting for sociodemographic variables, BMI, alcohol use, smoking status, comorbidities, and dietary factors (energy, fat, fiber, and cholesterol), the odds ratio (OR) for colorectal cancer was 0.86 (95% CI: 0.69-1.06, p = 0.162) per 100 mg higher choline intake. Across increasing quartiles of choline intake, a non-significant inverse trend was observed (Q4 vs. Q1 OR: 0.76, 95%CI: 0.37 ~ 1.55, P-trend = 0.23). Subgroup analyses revealed largely consistent associations, with a significant interaction by hypertension status (P-interaction =0.022). Conclusion: In this large, nationally representative sample of U.S. adults, higher dietary choline intake was not significantly associated with colorectal cancer odds after adjusting for potential confounders. However, a non-significant inverse trend was observed. Further prospective studies are needed to confirm these findings and elucidate the underlying mechanisms.

The effect of adjuvant chemotherapy on survival in node negative colorectal cancer with or without perineural invasion: a systematic review and meta-analysis.

Purpose: It was aimed at assessing the benefits of adjuvant chemotherapy (ACT) for patients with node-negative colorectal cancer (CRC) either with or without perineural invasion (PNI). Methods: We systematically searched PubMed, Cochrane Library, Embase, and Web of Science from database inception through October 1, 2023. Survival outcomes were analyzed using hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The methodological quality of included studies was assessed using the Newcastle-Ottawa Scale (NOS). Heterogeneity for the descriptive meta-analyses was quantified using the I2 statistic. Results: Ten studies included in this review. ACT improved overall survival (OS) (HR 0.52, 95% CI 0.40-0.69) and disease-free survival (DFS) (HR 0.53, 95% CI 0.35-0.82) in PNI + patients but did not affect DFS (HR 1.13, 95% CI 0.72-1.77) in PNI- patients. A disease-specific survival (DSS) benefit with chemotherapy was observed in PNI + (HR 0.76, 95% CI 0.58-0.99) and PNI- patients (HR 0.76, 95% CI 0.57-1.00). And PNI decreased DFS (HR 1.94, 95% CI 1.52-2.47) and OS (HR 1.75, 95% CI 0.96-3.17) in node-negative CRC. Conclusions: In conclusion, chemotherapy appears most beneficial for survival outcomes in node-negative patients with PNI, but may also confer some advantage in those without PNI.

Effect of Kegel Exercise Combined with a Therapeutic Apparatus for Electromyographic Feedback on Bladder Function in Patients with Bladder Injury during Rehabilitation.

OBJECTIVE: To explore the effect of Kegel exercise combined with a therapeutic apparatus for electromyographic feedback on bladder function in patients with bladder injury during rehabilitation. METHODS: The clinical data of 156 patients with bladder injury admitted to Wuxi Medical Center of Nanjing Medical University in the past 2 years were selected for retrospective analysis. The patients were divided into the reference group (RG, Kegel exercise, n = 83) and the study group (SG, Kegel exercise combined with a therapeutic apparatus for electromyographic feedback, n = 73) in accordance with different rehabilitation programmes. The urination conditions and urodynamic indices of the SG and RG after intervention were compared, and patients' mood states were evaluated with the hospital anxiety and depression scale (HADS). RESULTS: Compared with the RG, the SG had overtly lower bladder residual urine volume, daily urination frequency, detrusor pressure at the end of the filling period and detrusor leak-point pressure (all p < 0.001); Obviously higher urinary volume at each time and maximum bladder volume (all p < 0.001) and distinctly lower hospital anxiety and depression scale-anxiety (HADS-A) and hospital anxiety and depression scale-depression (HADS-D) scores after treatment (all p < 0.001). CONCLUSIONS: The application of Kegel exercise combined with a therapeutic apparatus for electromyographic feedback during the rehabilitation of patients with bladder injury can effectively improve the urination conditions, bladder function and mood states of the patients. Moreover, it can guarantee the return to normal life of the patients and improve their quality of life.

WTAP regulates autophagy in colon cancer cells by inhibiting FLNA through N6-methyladenosine.

Our study investigated the role of WTAP in colon cancer. We employed experiments including m6A dot blot hybridization, methylated RNA immunoprecipitation, dual-luciferase, and RNA immunoprecipitation to investigate the regulatory mechanism of WTAP. Western blot was performed to analyze the expression of WTAP, FLNA and autophagy-related proteins in cells. Our results confirmed the up-regulation of WTAP in colon cancer and its promoting effect on proliferation and inhibiting effect on apoptosis. FLNA was the downstream gene of WTAP and WTAP-regulated m6A modification led to post-transcriptional repression of FLNA. The rescue experiments showed that WTAP/FLNA could inhibit autophagy. WTAP-mediated m6A modification was confirmed to be crucial in colon cancer development, providing new insights into colon cancer therapy.

Association between niacin and mortality among patients with cancer in the NHANES retrospective cohort.

BACKGROUND: The vitamin niacin is used as a lipid-regulating supplement, but it is unknown whether niacin has a positive influence on cancer prognosis. In this study, we examine the relationship between niacin intake and mortality among patients with cancer. METHODS: Our study utilized all available continuous data from the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2014. Multivariable Cox regression models were applied in order to investigate dietary niacin intake's association with mortality. We compared the survival probability between groups of low and high niacin intake by plotting Kaplan-Meier curves. An analysis of subgroups was used to investigate heterogeneity sources. RESULTS: A total of 3504 participants were included in the cohort, with 1054 deaths. One thousand eight hundred forty-seven participants (52.3%) were female, 2548 participants (73.4%) were white, and the mean age (SE) was 65.38 years (0.32). According to multivariate logistic regression analysis, niacin intake was negatively associated with mortality outcomes in patients with cancer, with P values below 0.05 in all models. In subgroup analyses based on sex, age, and BMI, the association persisted. The Kaplan-Meier curves indicate that high niacin intake groups have better survival rates than low intake groups. Niacin supplementation improved cancer mortality but not all-cause mortality. CONCLUSION: According to our study, higher dietary niacin intake was associated with lower mortality in cancer patients. Niacin supplements improved cancer survival rates, but not all causes of mortality.

Efficacy of Laparoscopic Radical Resection Combined with Neoadjuvant Chemotherapy and Its Impact on Long-Term Prognosis of Patients with Colorectal Cancer.

Objective: The aim of the study is to examine the efficacy of laparoscopic radical resection of colorectal cancer combined with neoadjuvant chemotherapy and its impact on the overall prognosis of patients with colorectal cancer (CC). Methods: A total of 80 CC patients hospitalized and treated at our hospital between November 2019 and June 2021 were selected at random as research subjects and divided equally into two groups: the surgical group (n = 40) and the combination group (n = 40). Patients in the surgical group were treated with laparoscopic radical resection, while patients in the combination group received laparoscopic radical resection combined with neoadjuvant chemotherapy. The two groups were compared in terms of surgery-related indicators, tumor markers (serum carcinoembryonic antigen (CEA), glycoprotein 199 (CA199), vascular endothelial growth factor (VEGF), and matrix metalloproteinase 9 (MMP9)), postoperative complications, and 1-3 years postoperative survival rate and recurrence rate. Results: The surgical duration of the combination group was significantly shorter than the surgical group (P < 0.05). No significant differences were found in intraoperative blood loss, time to get out of bed, exhaust time, or hospital stay between the two groups (P < 0.05). In the combination group, serum tumor markers (carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), vascular endothelial growth factor (VEGF), and matrix metalloproteinase 9 (MMP9)) were markedly lower than those in the surgical group (P < 0.05). The combination group exhibited fewer postoperative complications than those in the operation group (P < 0.05). In the combination group, the 1-3 years postoperative survival rate was higher, while the 1-3 years postoperative recurrence rate was considerably lower than that in the surgical group (P < 0.05). Conclusion: CC patients benefit well from laparoscopic radical resection coupled with neoadjuvant chemotherapy. The approach is efficient in lowering blood tumor markers in patients and lowering the risk of surgery-related complications. It has the potential to enhance patients' long-term prognoses, allowing them to live longer and lower their chance of recurrence.

Examination of the effects of microRNA-145-5p and phosphoserine aminotransferase 1 in colon cancer.

Previous studies manifested that microRNA-145-5p is pivotal in the development of various cancers. Nevertheless, the potential function of microRNA-145-5p in colorectal cancer remains unclear. This study attempted to investigate the potential role and possible mechanism of microRNA-145-5p in colon cancer. MicroRNA-145-5p and phosphoserine aminotransferase 1 (PSAT1) levels in colon cancer cells were assayed via quantitative reverse transcription polymerase chain reaction (qRT-PCR). Cell proliferation and cell cycle status were assessed using Cell Counting Kit-8, colony formation, and flow cytometry. The target binding relationship of microRNA-145-5p and PSAT1 was identified using bioinformatics analysis and dual-luciferase reporter gene assay. The result of qRT-PCR disclosed that microRNA-145-5p was markedly down-regulated and PSAT1 level was up-regulated in colon cancer cell lines. Besides, enforced microRNA-145-5p level repressed proliferation of colon cancer cells, and cells were arrested in G0-G1 phase. Bioinformatics analysis and dual-luciferase reporter genes confirmed that PSAT1 was a downstream target of microRNA-145-5p. Enforced PSAT1 level remarkably modulated cell cycle and fostered cell proliferation. Furthermore, rescue experiments displayed that microRNA-145-5p restrained cell cycle progression and cell proliferation and forced PSAT1 level could partially reverse this process. Taken together, our findings demonstrated that microRNA-145-5p repressed colon cancer cell cycle progression and cell proliferation via targeting PSAT1. Our findings identified microRNA-145-5p as an essential tumor repressor gene in colon cancer and may provide a novel biomarker for colon cancer.

[Responses of solar-induced chlorophyll fluorescence to meteorological drought across the Loess Plateau, China.] / é»„åœŸé«˜åŽŸæ¤è¢«æ—¥å ‰è¯±å¯¼å¶ç»¿ç´ è§å ‰å¯¹æ°”è±¡å¹²æ—±çš„å“åº”.

With the intensification of climate change, the frequency, duration and scope of drought have become more and more serious. Exploring the responses of plant photosynthesis to drought and the impacts of meteorological factors on photosynthesis is of great significance to the dealing with drought stress. Solar-induced chlorophyll fluorescence (SIF) based on remote sensing has the potential for early monitoring and accurate assessment of regional vege-tation photosynthesis under drought conditions. Based on the spaceborne SIF information and the standardized precipitation evapotranspiration index (SPEI), we investigated the responses of vegetation photosynthesis to drought and the influence of meteorological factors in the growing season (April to October) of the Loess Plateau during 2001-2017. The results showed that about 87.8% of total areas of the Loess Plateau had a significant positive correlation between SIF and SPEI. Vegetation photosynthesis in semi-arid area was more sensitive to drought and less sensitive in semi-humid area. Different vegetation types had different photosynthetic responses to drought. Grassland had the highest sensitivity to drought with three to four months SPEI time-scale, while forest had the lowest sensiti-vity with three to ten months SPEI time-scale. There was a significant correlation between meteorological factors and SIF. Temperature and precipitation were the most important factors affecting vegetation photosynthesis on the Loess Plateau. Photosynthetically active radiation showed a similar controlling strength to temperature. The impacts of drought and meteorological factors on vegetation photosynthesis were largely determined by differences in drought resistance among ecosystem types and climate regions.
