IntroductionDepression might affect women with cervical cancer and can deteriorate their quality of life or even their compliance with cancer treatments. The aim of this study was to investigate the incidence of depression and risk factors for developing depression among women with cervical cancer in Taiwan.Patients and methodsThis study enrolled patients with newly diagnosed cervical cancer from the National Health Insurance Research Database in Taiwan. From a population of 21,400,826 residents, each cervical cancer patient was matched with one subject without cervical cancer according to sex, age, and comorbidities with the same diagnostic index. The International Classification of Diseases, Ninth Revision, code 180.9 was used to identify patients with cervical cancer, and 296.0X–296.1X, 296.4X–296.8X, 296.2X–296.3X, 300.4, and 311.X codes were used to identify those with depressive disorders.ResultsIn total, 19,316 newly diagnosed cervical cancer patients were enrolled from January 2000 to December 2005, and the median follow-up period was 5.23 years (1.75–8.48 years). The prevalence of depressive disorder was 4.21% (813 of 19,316) in the cervical cancer cohort, and it was 3.85% (744 of 19,316) in the control cohort. The incidence risk ratio of depressive disorders was 1.35 (95% CI =1.22–1.49, P<0.001) among these cervical cancer patients. Cervical cancer, as an independent risk factor, was associated with developing subsequent depressive disorder. In addition, being older (≥65 years old) and the comorbidities of diabetes mellitus, ischemic heart disease, and cerebrovascular disease were also risk factors for predicting depressive disorder in cervical cancer patients.DiscussionCervical cancer is a prominent risk factor for the development of depression in women with cervical cancer in Taiwan. The patients with comorbidities, including diabetes mellitus, ischemic heart disease, and cerebrovascular disease, have higher risks of developing depression. However, there were no significant differences among the cervical cancer treatment modalities. In conclusion, these patients require early psychological support and intervention.
Normative data for ultrasonographic measurements of maxillary and mandibular lengths within the Taiwanese population were presented. Our data can serve as a reference value in congenital anomaly screening during prenatal examination.
The current enhanced permeability and retention (EPR)-based approved nanomedicines have had little impact in terms of prolongation of overall survival in patients with cancer. For example, the two Phase III trials comparing Doxil ® , the first nanomedicine approved by the US Food and Drug Administration, with free doxorubicin did not find an actual translation of the EPR effect into a statistically significant increase in overall survival but did show less cardiotoxicity. In the current work, we used a two-factor factorial experimental design with intraperitoneal versus intravenous delivery and nanomedicine versus free drug as factors to test our hypothesis that regional (intraperitoneal) delivery of nanomedicine may better increase survival when compared with systemic delivery. In this study, we demonstrate that bypassing, rather than exploiting, the EPR effect via intraperitoneal delivery of nanomedicine harboring a sustained-release function demonstrates dual pharmacokinetic advantages, producing more efficient tumor control and suppressing the expression of stemness markers, epithelial-mesenchymal transition, angiogenesis signals, and multidrug resistance in the tumor microenvironment. Metastases to vital organs (eg, lung, liver, and lymphatic system) are also better controlled by intraperitoneal delivery of nanomedicine than by standard systemic delivery of the corresponding free drug. Moreover, the intraperitoneal delivery of nanomedicine has the potential to replace hyperthermic intraperitoneal chemotherapy because it shows equal efficacy and lower toxicity. In terms of efficacy, exploiting the EPR effect may not be the best approach for developing a nanomedicine. Because intraperitoneal chemotherapy is a type of regional chemotherapy, the pharmaceutical industry might consider the regional delivery of nanomedicine as a valid alternative pathway to develop their nanomedicine(s) with the goal of better tumor control in the future.
3DPDUS can be used to assess the fetal MOV and blood flow development quantitatively. Our study indicated that fetal MOV and blood flow correlated significantly with the advancement of gestational age. This information may serve as reference data for further studies of the fetal brain and blood flow under abnormal conditions.
