Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 4, doi: 10.1007/s11783-019-1143-2

Abstract:

Specific second-order rate constants were determined for 5-FU and CAP with ozone.

Reaction sites were confirmed by kinetics, Fukui analysis, and products.

The olefin moiety was the main ozone reaction site for 5-FU and CAP.

Carboxylic acids comprised most of the residual TOC for 5-FU.

Ozonation removed the toxicity associated with 5-FU and products but not CAP.

Factors related to compliance with oral analgesic treatment of inpatients with chronic pain

Hong Zhu,Yuzhu Zheng,Hui Gao,Li Liu,Lie Yang

Frontiers of Medicine 2015, Volume 9, Issue 3,   Pages 374-379 doi: 10.1007/s11684-015-0411-1

Abstract:

This study aimed to determine the relationship between the different factors of analgesic therapy and the compliance of chronic pain inpatients. We prospectively investigated 100 consecutive inpatients with non-cancer chronic pain who were hospitalized to receive oral analgesic treatment in the Pain Department of West China Hospital from May 2013 to October 2013. Patients who completed the treatment plan were recorded as good compliance, whereas patients who partly completed or even refused the treatment were recorded as moderate or non-compliance, respectively. A total of 73 (73.7%), 17 (17.1%), and 9 (9.2%) patients showed good, moderate, and non-compliance, respectively. Univariate analyses showed significantly better compliance among farmers, patients educated in college or above, with family income of<3000 CNY, and with severe or moderate pain than those employed and unemployed (P=0.02), patients educated below college (P=0.013), with family income of≥3000 CNY (P=0.025), and with mild pain (P<0.001), respectively. Logistic regression analysis showed that the family income of≥3000 CNY (OR: 2.50, 95%CI: 1.65–4.51, P=0.021) and mild pain (OR: 1.27, 95%CI: 1.03–3.31, P=0.016) were associated with moderate or non-compliance with oral analgesic treatment. In conclusion, the low compliance with oral treatment of analgesics was found in Chinese inpatients with chronic pain and compliance was negatively associated with family income and degree of pain of patients.

Theoretical insights into influence of additives on sulfamethoxazole crystal growth kinetics and mechanisms

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1503-1515 doi: 10.1007/s11705-022-2294-4

Abstract: In this work, the influence of the initial chemical potential gradient, stirring speed, and polymer type on sulfamethoxazole (SMX) crystal growth kinetics was systematically investigated through density functional theory (DFT) calculations, experimental measurements and the two-step chemical potential gradient model. To investigate the influence of different conditions on the thermodynamic driving force of SMX crystal growth, SMX solubilities in different polymer solutions were studied. Four model polymers effectively improved SMX solubility. It was further found that polyvinylpyrrolidone (PVP) and hydroxypropyl methyl cellulose (HPMC) played a crucial role in inhibiting SMX crystal growth. However, polyethylene glycol (PEG) promoted SMX crystal growth. The effect of the polymer on the crystal growth mechanisms of SMX was further analyzed by the two-step chemical potential gradient model. In the system containing PEG 6000, crystal growth is dominated by the surface reaction. However, in the system containing PEG 20000, crystal growth is dominated by both the surface reaction and diffusion. In addition, DFT calculations results showed that HPMC and PVP could form strong and stable binding energies with SMX, indicating that PVP and HPMC had the potential ability to inhibit SMX crystal growth.
