RESUMEN
AIMS AND OBJECTIVES: Current knowledge of patients' preferences for rheumatoid arthritis (RA) treatment is limited. Our goal was to determine the most favorable mode of therapy and the reasons behind choosing each route among RA patients in the Rheumatoid Arthritis Saudi Database (RASD). MATERIALS AND METHODS: In this cross-sectional, nationwide, qualitative study, we conducted interviews with 308 RA patients to assess their preferred mode of therapy (oral, subcutaneous (SC) injection, or intravenous (IV) infusion) and to determine the reasons behind their choice. The determining factors behind patients' preferred mode of therapy were evaluated using a 10-point allocation system (1 = least important, 10 = most important). RESULTS: We interviewed 308 RA patients (83.4% females, mean age, 48 years). Among all administration modes, the oral route was identified as the most preferred mode among our patients, with a percentage of 73.3%, followed by SC injection and IV infusion at 19.5% and 7.3%, respectively. Ease of drug administration was the most reported reason for patients who chose the oral route over the injection route (63.2%). Difficulty remembering to take the drug and finding it hard to swallow the pills were the highest-scored reasons for avoiding the oral route (24.9%). CONCLUSION: Our study demonstrates and emphasizes the importance of shared decision-making between patients and their physicians. The oral route of therapy is, by far, the most preferred mode among our cohort of RA patients.
RESUMEN
This study was on the optoelectronic properties of multilayered two-dimensional MoS2 and WS2 materials on a silicon substrate using sputtering physical vapor deposition (PVD) and chemical vapor deposition (CVD) techniques. For the first time, we report ultraviolet (UV) photoresponses under air, CO2, and O2 environments at different flow rates. The electrical Hall effect measurement showed the existence of MoS2 (n-type)/Si (p-type) and WS2 (P-type)/Si (p-type) heterojunctions with a higher sheet carrier concentration of 5.50 × 105 cm-2 for WS2 thin film. The IV electrical results revealed that WS2 is more reactive than MoS2 film under different gas stimuli. WS2 film showed high stability under different bias voltages, even at zero bias voltage, due to the noticeably good carrier mobility of 29.8 × 102 cm2/V. WS2 film indicated a fast rise/decay time of 0.23/0.21 s under air while a faster response of 0.190/0.10 s under a CO2 environment was observed. Additionally, the external quantum efficiency of WS2 revealed a remarkable enhancement in the CO2 environment of 1.62 × 108 compared to MoS2 film with 6.74 × 106. According to our findings, the presence of CO2 on the surface of WS2 improves such optoelectronic properties as photocurrent gain, photoresponsivity, external quantum efficiency, and detectivity. These results indicate potential applications of WS2 as a photodetector under gas stimuli for future optoelectronic applications.
RESUMEN
This study was designed to investigate the effect of prenatal exposure to synthetic sex steroid on sperm quantity and quality, relative testicular and epididymal weights, and reproductive hormones level in adult Wistar rats. Forty male Wistar rats were divided into two groups: a test group (n = 20) that included mature rats that were born to dams exposed to gestational treatment with hydroxyprogesterone and a control group (n = 20) that included mature rats born to untreated dams. Compared to the control group, the test group showed a significant reduction in the sperm count, viability and motility, relative testicular and epididymal weights together with increased abnormal spermatozoa (p < 0.001). The reproductive hormonal assay revealed significantly lower serum testosterone and higher levels of FSH and LH among the test groups compared to the control (p < 0.05 for all). Prenatal exposure to synthetic progesterone negatively affected sperm production and function, relative testicular and epididymal weights, and reproductive hormone levels.
