Purpose: Numerous studies have produced conflicting findings regarding the efficacy of statins in prostate cancer treatment. Our objective was to examine the correlation between statin usage and clinical outcomes in Taiwanese men with de novo metastatic prostate cancer. Materials and Methods: We identified patients diagnosed with de novo metastatic prostate cancer from the Chang Gung Research Database spanning the years 2007 to 2020. To minimize confounding bias, we employed the inverse probability of treatment weighting (IPTW) method. Clinical outcomes were assessed using IPTW-adjusted Kaplan-Meier curves. Multivariate Cox proportional hazard regression analysis was utilized to evaluate the association between mortality and clinical factors. Results: The study cohort comprised 1,716 statin users and 276 non-users. Patients who used statins exhibited a longer median overall survival (85.4 months compared to 58.2 months; p=0.001) and cancer-specific survival (112.6 months compared to 75.7 months; p<0.001) compared to non-users. The median time to the development of castration-resistant status was similar between statin users and non-users (p=0.069). Multivariable Cox proportional hazards regression analysis, after IPTW adjustment, demonstrated that statin use was associated with improved overall survival. Conclusions Our study indicates that the use of statins following a de novo metastatic prostate cancer diagnosis enhances survival outcomes. However, statins did not appear to delay the onset of castration-resistant status. Further large-scale and long-term studies are warranted to investigate the biological effects of statins in men with prostate cancer.

Preeclampsia and intrauterine growth restriction (IUGR) of the fetus are the two most common pregnancy complications worldwide, affecting 5%-10% of pregnant women. Preeclampsia is associated with significantly increased maternal and fetal morbidity and mortality. Hypoxia-induced uteroplacental dysfunction is now recognized as a key pathological factor in preeclampsia and IUGR. Reduced oxygen supply (hypoxia) disrupts mitochondrial and endoplasmic reticulum (ER) function. Hypoxia has been shown to alter mitochondrial reactive oxygen species (ROS) homeostasis and induce ER stress. Hypoxia during pregnancy is associated with excessive production of ROS in the placenta, leading to oxidative stress. Oxidative stress occurs in a number of human diseases, including high blood pressure during pregnancy. Studies have shown that uterine placental tissue/cells in preeclampsia and IUGR show high levels of oxidative stress, which plays an important role in the pathogenesis of both the complications. This review summarizes the role of hypoxia-induced mitochondrial oxidative stress and ER stress in the pathogenesis of preeclampsia/IUGR and discusses the potential therapeutic strategies targeting oxidative stress to treat both the pregnancy complications.

OBJECTIVE: To evaluate the value of Gerota's fascia suspension device in retroperitoneal laparoscopic partial nephrectomy, and to share the operation experience. METHODS: From October 2018 to December 2020, 6 cases of tumor located in the ventral side of the kidney were selected, including 3 males and 3 females, with 3 cases on the right side and 3 cases on the left side, aged 38-60 years, with an average of 52 years. The body mass index (BMI) was 18.3-30.2 kg/m², with an average of 22.9 kg/m². One patient with diabetes mellitus, three patients with renal cysts, and two patients underwent cholecystectomy before. All the patients were found by physical examinations. The course of disease was 7 days to 20 years, with a median time of 1 month. The tumor was in the ventral side of the kidney, 2 cases located in the upper pole, 1 case in the lower pole and 3 cases near the renal hilum. The tumor size was 1.2-7.8 cm, with an average of 4.5 cm. The R.E.N.A.L score was 7 in 1 case, 8 in 3 cases and 9 in 2 cases. After the preoperative examination completed, retroperitoneal laparoscopic partial nephrectomy (Gerota's fascia suspension device) was performed. RESULTS: All the operations were successfully completed. The operation time ranged from 139 to 193 min, with an average of 172 min. The renal artery occlusion time was 7-43 min, with an average of 19 min, only one case was more than 30 min. The blood loss ranged from 10 to 500 mL, with an average of 128 mL. The postoperative hospital stay ranged from 4 to 13 days, with an average of 6.5 days. Postoperative pathology revealed 4 cases of renal angiomyolipoma and 2 cases of renal clear cell carcinoma. The patients were followed up for 2-27 months, with an average of 17 months, without recurrence. CONCLUSION In the operation of retroperitoneal laparoscopic partial nephrectomy, Gerota's fascia suspension device is beneficial to expose the ventral surgical field, and it is convenient for the surgeon to operate with both hands. This technique is an effective method to deal with the ventral renal tumor, which is worthy of promotion.

Purpose: To assess characteristics the application of mobile medication system and medication administration error (MAE) alerts in a general hospital. Methods: The subject hospital adopted a mobile medication system in 2016. All medication administrations in the general wards and ICUs were automatically recorded in real-time using identification barcodes, drug barcodes, and hand-held point-of-care devices. MAE alert logs were recorded from April 1st 2017 to March 31st 2018. For this study analysis was done using Pearson’s chi-squared test for potentially related factors of MAE alerts included administration time, order type, medication route, and length of nurse’s employment. Results: The total number of medications during the period of this study was 3,227,990. Among them, 2,698,317 medication doses were recorded, resulting in the system application rate of 83.6%. The system application rate was significantly correlated with all factors related to potential MAE alters. In this study 23,314 MAE alerts(0.9% of the total medication doses) were identified. The MAE alerts were related to new (OR=2.26, p<.001) and emergency (OR=2.25, p<.001) orders, and administration at a non-standard time (OR=2.032, p<.001). Medication route (p<.001), and nurse’s employment duration(p<.001) were also related. Conclusion A mobile medication system contributes to improving patient safety by preventing potential MAEs. The MAE alerts were related to administration time, order type, medication route, and duration of nurse’s employment. In order to prevent medication administration errors, it is necessary to standardize the process of medication and create an environment in which medication administration can be performed in a planned situation.

Objective To establish a predictive model for inpatients of cardio-cerebrovascular disease in rural areas of Wugang through time series analysis, and predict the changing trend of cardio-cerebrovascular disease, so as to offer guidance for the health care resources allocation and prevention and control of cardio-cerebrovascular disease. Methods The seasonal autoregressive integrated moving average model (SARIMA) was constructed based on the monthly number of cases of cardio-cerebrovascular disease in rural areas from January 2013 to December 2016 by Stata 14.0 software, and the predictive effect of the model was verified with the monthly number of inpatients of cardio-cerebrovascular disease in 2017. Results The final fitting model of inpatients of cardio-cerebrovascular disease was SARIMA (2, 1, 1)×(0, 1, 0)12. The residual sequence of the model was diagnosed. Results of Ljung-Box Q test showed that the residual sequence was white noise sequence (Q=11.12, P=0.68). In addition, the 2017 forecast was basically consistent with the observations, the overall relative error was around -1.2%. The results showed that the summer was the peak period of cardiovascular and cerebrovascular hospitalization. Conclusion SARIMA model can accurately predict the number of inpatients of cardio-cerebrovascular disease in Wugang, which can provide data support for the hospital administrator to rationally allocate medical resources in the cardiovascular according to the needs of cardio-cerebrovascular treatment in different months.

Objective: To analyze the hearing self-protection behavior patterns and internal factors of workers exposured to occupational noise in an aircraft manufacturing industry based on health belief model, so as to provide reference for further health promotion programs and intervention measures. Methods: A total of 1600 front-line workers were selected from 10 units of an aircraft manufacturing enterprise by cluster sampling method. The basic and occupational information of employees were collected, and a self-reported questionnaire was designed according to the health belief model to acquire the hearing self-protection behaviors of workers. Results: There were significant differences in the perceived severity, perceived benefit, perceived impairment, self-efficacy and behavioral incentive scores of different hearing self-protection behaviors among the noise-causing workers (P<0.05). There were significant differences in the distribution of hearing self-protection behaviors among different genders, ages, education levels, length of service, initial noise exposure time and cumulative noise reception time (P<0.05). The perceived benefits, perceived barriers, behavioral incentives, self-efficacy scores, and educational attainment of the noise-causing workers were all related to the type of hearing self-protection behavior (P<0.05) . Conclusion The educational level and health belief model can predict the hearing self-protection behavior patterns of front-line workers to some extent, more attention should be paid to the monitoring of the well-educated employees.
