In this work, fibrous silica-titania (FST) was successfully prepared by the microemulsion method prior to the addition of three types of carbonaceous materials: graphitic-carbon nitride, g-C3N4 (CN), graphene nanoplatelets (GN), and multi-wall carbon nanotubes, MWCNT (CNT), via a solid-state microwave irradiation technique. The catalysts were characterized using XRD, FESEM, TEM, FTIR, UV-Vis DRS, N2 adsorption-desorption, XPS and ESR, while their photoactivity was examined on the degradation of toxic 2-chlorophenol (2-CP). The result demonstrated that the initial reaction rate was in the following order: CNFST (5.1 × 10-3 mM min-1) > GNFST (2.5 × 10-3 mM min-1) > CNTFST (2.3 × 10-3 mM min-1). The best performance was due to the polymeric structure of g-C3N4 with a good dispersion of C and N on the surface FST. This dispersion contributed towards an appropriate quantity of defect sites, as a consequence of the greater interaction between g-C3N4 and the FST support, that led to narrowed of band gap energy (2.98 eV to 2.10 eV). The effect of scavenger and ESR studies confirmed that the photodegradation over CNFST occurred via a Z-scheme mechanism. It is noteworthy that the addition of green carbonaceous materials on the FST markedly enhanced the photodegradation of toxic 2-CP.

INTRODUCTION: Dysphagia is a common disorder among stroke patients. Dysphagia can lead to consequences that can negatively impact the quality of life (QoL) in stroke patients.
AIM: To investigate the impact of dysphagia on the QoL in stroke patients.
METHODS: Relevant types of literature were searched from PubMed, Scopus, ProQuest, and Google Scholar databases from inception to July 2022. Peerreviewed studies that aimed to determine the impact of dysphagia on the QoL in stroke patients were included regardless of the year of publication. The National Institutes of Health tool for observational cohort and cross-sectional studies was used to assess the methodological quality of the selected studies. In addition, data analysis was conducted using qualitative methodology with narrative synthesis.
RESULTS: A total of 6 studies met the inclusion criteria with a total number of 381 participants. Only one study has good methodological quality while other studies have fair methodological quality. Dysphagia negatively impacts the QoL in stroke patients, especially those with severe dysphagia. However, after treatment, changes were evident through improved QoL and decreased severity of dysphagia. Moreover, the research found that patients with a higher educational level have a better QoL.
CONCLUSION: Dysphagia has a negative impact on the QoL in stroke patients, so dysphagia in stroke patients should be diagnosed and treated as soon as possible to avoid poor QoL.
