A positive association between RDW and coronary heart disease in the rheumatoid arthritis population: A cross-sectional study from NHANES.

Previous research has indicated that higher red blood cell distribution width (RDW) increases the risk of coronary heart disease. However, no studies have established a link between RDW and coronary heart disease in the rheumatoid arthritis population. This research aims to explore the association between RDW and coronary heart disease among individuals with rheumatoid arthritis. We selected demographic data, laboratory data, lifestyle, and medical history from the National Health and Nutrition Examination Survey (NHANES), specifically including age, gender, poverty, RDW, race, BMI, diabetes, education, coronary heart disease, hypertension, cholesterol, smoking, and drinking. RDW and coronary heart disease were found to have a positive association in the rheumatoid arthritis population (OR = 1.145, 95%CI: 1.036-1.266, P = .0098), even after adjusting for factors such as age, gender, race, education level, smoking, and drinking. Subgroup analysis showed a stronger positive association, particularly in individuals aged 55-66 years, males, and the Hispanic White population with diabetes or hypercholesterolemia. There is a significant correlation between RDW and coronary heart disease among individuals with rheumatoid arthritis.

The application of Foley catheter traction technique in extraperitoneal robot-assisted radical prostatectomy.

OBJECTIVES: To describe a technique to improve exposure of prostate during extraperitoneal robot-assisted radical prostatectomy (EP-RARP). MATERIAL AND METHODS: From March 2020 to June 2022, a total of 41 patients with prior intra-abdominal surgery underwent EP-RARP. Twenty-three patients improved exposure by traction of prostate through urinary catheter. The catheter traction prostatectomy (CTP) group was compared with the standard prostatectomy (SP) group using three robotic arms (18 patients) in terms of estimated blood loss (EBL), operative time, positive surgical margin rate, the recovery rate of urinary continence, Gleason score and postoperative hospital stays. Differences were considered significant when P < 0.05. RESULTS: The operative time was lower in the CTP group (109.63 min vs. 143.20 min; P < 0.001). EBL in the CTP group was 178.26 ± 30.70 mL, and in the standard prostatectomy group, it was 347.78 ± 53.53 mL (P < 0.001). No significant differences with regard to postoperative hospital stay, recovery rate of urinary continence, catheterization time and positive surgical margin were observed between both groups. No intraoperative complications occurred in all the patients. After 6 months of follow-up, the Post-op Detectable prostate specific antigen was similar between the two groups. CONCLUSION: CTP is a feasible, safe, and valid procedure in EP-RARP. Application of CTP improved the exposure of prostate, reduced operative time and blood loss in comparison with the conventional procedure.

Effect comparisons of different conditioners and microbial agents on the degradation of estrogens during dairy manure composting.

To investigate the degradation efficiency of conditioners and commercial microbial agents on estrogens (E1, 17α-E2, 17ß-E2, E3, EE2, and DES) in the composting process of dairy manure, seven different treatments (RHB-BF, OSP-BF, SD-BF, MR-BF, MR-FS, MR-EM, and MR-CK) under forced ventilation conditions were composted and monitored regularly for 30 days. The results indicated that the removal rates of estrogens in seven treatments ranged from 95.35% to 99.63%, meanwhile the degradation effect of the composting process on 17ß-Estradiol equivalent (EEQ) was evaluated, and the removal rate of ΣEEQ ranged from 96.42% to 99.72%. With the combined addition of rice husk biochar (RHB) or oyster shell powder (OSP) and bio-bacterial fertilizer starter cultures (BF), namely RHB-BF and OSP-BF obviously promoted the rapid degradation of estrogens. 17ß-E2 was completely degraded on the fifth day of composting in OSP-BF. Microbial agents have some promotional effect and enhances the microbial degradation of synthetic estrogen (EE2, DES). According to the results of RDA, pH and EC were the main environmental factors affecting on the composition and succession of estrogen-related degrading bacteria in composting system. As predominant estrogens-degrading genera, Acinetobacter, Bacillus, and Pseudomonas effected obviously on the change of estrogens contents. The research results provide a practical reference for effective composting of dairy manure to enhancing estrogens removal and decreasing ecological risk.

The application of internal traction technique in retroperitoneal robot-assisted partial nephrectomy for renal ventral tumors.

BACKGROUND: For patients with prior intra-abdominal surgery or multiple arteries, the retroperitoneal robot-assisted partial nephrectomy (rRAPN) is a better choice. The renal ventral tumor poses an additional challenge due to poor tumor exposure. This study is determined to assess the feasibility of an internal traction technique (ITT) in rRAPN for the management of renal ventral tumors. METHODS: From November 2019 to March 2021, a total of 28 patients with renal ventral tumor underwent rRAPN. All patients had prior abdominal surgery or multiple arteries. The ITT group (20 patients), which improved the tumor exposure by traction of the kidney with suture, was compared with the traditional technique group (8 patients) in terms of warm ischemia time, estimated blood loss and postoperative hospital stay, retroperitoneal drainage, R.E.N.A.L. score, and serum creatinine. Differences were considered significant when P < 0.05. RESULTS: All rRAPN surgeries were successful without conversion to radical nephrectomy or open partial nephrectomy. The warm ischemia time was lower in the ITT group (17.10 min vs. 24.63 min; P < 0.05). Estimated blood loss in the traditional technique group was 324.88 ± 79.42 mL, and in the ITT group, it was 117.45±35.25 mL (P < 0.05). No significant differences with regard to postoperative hospital stay, retroperitoneal drainage, R.E.N.A.L. score, and serum creatinine were observed between both groups. Surgical margins were negative and no intraoperative complications occurred in all the patients. After 10 months of follow-up, no recurrence or metastasis occurred in all cases. CONCLUSION: ITT is a feasible, safe, and valid procedure in rRAPN for renal ventral tumors. Application of ITT improved the exposure and reduces warm ischemic time in comparison with the conventional procedure.

[Influencing Mechanism of Eh, pH and Iron on the Release of Arsenic in Paddy Soil].

The massive release of soil arsenic and its enrichment in rice are significantly associated with the flooded and anaerobic management in paddy soil. Soil redox potential (Eh), pH and iron oxides exert remarkable impacts on arsenic release, which remain to be explored. In this study, long-term aerobic and anaerobic as well as intermittent aerobic incubation treatments were applied to investigate the influences of Eh, pH and iron content on arsenic release. It was found that anaerobic and flooded treatment contributed to the highest arsenic release. With decreasing Eh, significant enhancement in As(Ⅲ) and As(Ⅴ) contents in soil solution was observed. Particularly, As(Ⅲ) and As(Ⅴ) contents during the second phase increased by 1.37 and 0.99 µg·L-1compared with those in the first phase. Conversely, significant reduction in soil arsenic release (P<0.05) occurred when intermittent aerobic treatment was adopted, and the lowest level of arsenic release was observed along with the longest treatment time (6 d). The exponent relationships between arsenic and soil Eh, pH and Fe2+ content were also established, which indicated that arsenic release could be accelerated by lower pH and elevated Eh. In addition, a significant positive correlation was also found between iron(Ⅱ) content and arsenic content in soil solution. Since low Eh and elevated pH served as critical factors driving arsenic release, intermittent and aerobic water management was proved to be an effective method for the inhibition of arsenic release and uptake and accumulation of arsenic by rice.

The antitumor and antioxidative activities of polysaccharides isolated from Isaria farinosa B05.

The water-soluble intra-polysaccharides WIPS1 and water-soluble extra-polysaccharides WEPS1 were isolated from Isaria farinosa B05 through ethanol precipitation and gel permeation chromatography (GPC). Their characteristics were determined by chemical analysis, gas chromatography, GPC and IR spectroscopy. The results show that WIPS1 contained 90.3% carbohydrate, 8.00% uronic acid, 7.15% protein and three kinds of monosaccharides including mannose, galactose and glucose with a molar ratio of 8.0:4.8:1.0. WEPS1 contained 93.4% carbohydrate, 8.06% uronic acid, 4.40% protein and three kinds of monosaccharides including mannose, galactose and glucose with a molar ratio of 21.6:4.7:1.0. WIPS1 and WEPS1 had a molecular weight of 42 and 208kDa, respectively. The in vivo tests in mice indicate that WIPS1 and WEPS1 had significant antitumor and antioxidative activities to some extent.
