Objectives
The aim of this study was to investigate the knowledge, attitude, and practice (KAP) of healthcare providers regarding the utilization of oxytocin for induction or augmentation of labor.
Methods
A qualitative study composed of direct observation and individual interview was conducted at a national tertiary maternity hospital in Phnom Penh, Cambodia in January and February 2013. The progress of labor in women who received oxytocin for induction or augmentation of labor was directly observed to confirm the healthcare providers’ management of oxytocin infusion. The attending doctors and midwives were individually interviewed after the women delivered.
Results
During the study period, 10 women were observed, and 12 healthcare providers (three doctors and nine midwives) were interviewed individually. Indications for labor induction or augmentation seemed to be appropriate for nine women. However, we found discrepancies between the national protocol and healthcare providers’ knowledge and actual practices. For example, 11 healthcare providers had never read the national protocol for the management of labor induction and augmentation, which implied limited access to the correct knowledge. A misconception was noted in that the sudden increase of oxytocin was not dangerous during the second stage of labor, despite the establishment of a good contraction pattern. Furthermore, a lack of unified initial dose and extremely high maximum dose above that recommended by the national protocol were observed. About half of observed women were not monitored for more than 2 hours from the beginning of oxytocin infusion.
Conclusion
In the present study, lack of knowledge, misconceptions regarding the management of oxytocin infusion, and a large gap between the national protocol and the actual clinical practices were confirmed. To maximize patient safety and therapeutic benefit, dissemination of the national protocol through in-service training is required.

Objective:
Folate receptor α (FRα) is a membrane protein expressed in various solid tumors but has limited expression in normal cells. Therefore, FRα is an attractive target for cancer treatment. This study aimed to investigate the relationship between FRα expression and the clinicopathological characteristics and survivals of cervical cancer.
Methods:
This retrospective study included patients with cervical cancer who underwent primary surgery between 2000 and 2020 at our institution. Immunohistochemical staining of FRα was performed using an anti-folate-binding protein/FBP antibody. FRα-positive staining was defined as ≥5% of tumor staining and FRα-high as ≥50% tumor staining with ≥2+ intensity. The association between FRα expression and survival was assessed using multivariate Cox regression analysis, adjusting for established prognostic factors.
Results:
Overall, 123 patients were identified, and 140 tumor samples, including 17 paired primary and metastatic samples, were evaluated. As histological types, 67 patients had squamous cell carcinoma (SCC), and 56 patients had non-SCC. All primary tumors were FRα-positive. High FRα expression was observed in 25% of the cases and differed according to histology (SCC vs. non-SCC, 14.9% vs. 37.5%, p=0.004). FRα expression was significantly higher in metastatic tumors than in primary (170 [IQR, 140–205] vs. 125 [IQR, 110–150], p=0.0006). High FRα expression was significantly associated with worse overall survival (hazard ratio, 6.73; 95% confidence interval, 2.21–20.53; p=0.001).
Conclusion
In cervical cancer, FRα expression was elevated in metastatic tumors and high expression was associated with a worse prognosis. Our study supports the development of FRα-targeted therapy for advanced cervical cancer.
