Factors influencing the degree of participation in surgical decision-making among Chinese patients with prostate cancer:A qualitative research

Objective:There was increasingly demand of participation in surgical decision-making among Chinese patients with prostate cancer.However,due to the complex healthcare system and advanced care settings,it is quite challenging for the patients to gain sufficient support from the institute and the government.This research aimed to investigate the factors that impact the degree of participation in surgical decision-making among Chinese prostate cancer patients.Methods:A phenomenological approach of qualitative research based on the results of semi-structured interviews was adopted,to explore the influencing factors which hinder the participation in surgical decision-making.Consolidated Criteria for Reporting Qualitative Research were utilized.Up to 160 post-operative patients who had undergone radical prostatectomy along with 68 medical and nursing staffs,were purposively recruited in this research.This retrospective study was carried out from September 2018 to August 2019.After recording and transcribing the interviews,the interview materials were evaluated via the Colaizzi's seven step approach and the NVivo Version 10 software to analyze the interview content.Results:According to the analysis and summary of the interviews,there were three factors affecting the degree of participation in surgical decision-making.Firstly,insufficient information was provided by medical and nursing staffs because of their lack of time,proper communication skills,and career experience,as well as difficulties in the development of patient decision aid and inconsistent resource availability.Secondly,the cognitive level of decision-making among patients was relatively low due to poor psychological endurance,insufficient amount of education,senility,and less knowledge and information demand.Ultimately,decisions were constantly made by family members with/without patients.Conclusions:The degree of participation of Chinese prostate cancer patients in the surgical decision-making had much space for improvement.

Synthesis,characterization,and photocatalytic activity of porous La–N–co-doped TiO_2 nanotubes for gaseous chlorobenzene oxidation

The photocatalytic oxidation of gaseous chlorobenzene（CB） by the 365 nm-induced photocatalyst La/N–Ti O2, synthesized via a sol–gel and hydrothermal method, was evaluated. Response surface methodology（RSM） was used to model and optimize the conditions for synthesis of the photocatalyst. The optimal photocatalyst was 1.2La/0.5N–Ti O2（0.5） and the effects of La/N on crystalline structure, particle morphology, surface element content, and other structural characteristics were investigated by XRD（X-ray diffraction）, TEM（Transmission Electron Microscopy）, FTIR（Fourier transform infrared spectroscopy）, UV–vis（Ultraviolet–visible spectroscopy）, and BET（Brunauer Emmett Teller）. Greater surface area and smaller particle size were produced with the co-doped Ti O2 nanotubes than with reference Ti O2. The removal of CB was effective when performed using the synthesized photocatalyst,though it was less efficient at higher initial CB concentrations. Various modified Langmuir-Hinshelwood kinetic models involving the adsorption of chlorobenzene and water on different active sites were evaluated. Fitting results suggested that competitive adsorption caused by water molecules could not be neglected, especially for environments with high relative humidity. The reaction intermediates found after GC–MS（Gas chromatography–mass spectrometry） analysis indicated that most were soluble, low-toxicity, or both. The results demonstrated that the prepared photocatalyst had high activity for VOC（volatile organic compounds） conversion and may be used as a pretreatment prior to biopurification.
