Previous researches have shown that anesthetic techniques can influence the patient outcomes of cancer surgery. Here, we studied the relationship between type of anesthetic and patient outcomes following elective, open pancreatic cancer surgery. This was a retrospective cohort study of patients who received elective, open pancreatic cancer surgery between January 2005 and July 2018. Patients were grouped according to the anesthesia they received, namely desflurane or propofol. A Kaplan-Meier analysis was conducted, and survival curves were presented from the date of surgery to death. Univariable and multivariable Cox regression models were used to compare hazard ratios for death after propensity matching. Subgroup analyses were performed for all-cause mortality, cancer-specific mortality, and disease progression. A total of 68 patients (56 deaths, 82.0%) under desflurane anesthesia, and 72 patients (43 deaths, 60.0%) under propofol anesthesia were included. Fifty-eight patients remained in each group after propensity matching. The propofol anesthesia was associated with improved survival (hazard ratio, 0.65; 95% confidence interval, 0.42-0.99; P = 0.047) in the matched analysis. Subgroup analyses showed significantly better cancer-specific survival (hazard ratio, 0.63; 95% confidence interval, 0.40-0.97; P = 0.037) in the propofol group. Additionally, patients under propofol had less postoperative recurrence, but not fewer postoperative metastases formation, than those under desflurane (hazard ratio, 0.55; 95% confidence interval, 0.34-0.90; P = 0.028) in the matched analysis. In a limited sample size, we observed that propofol anesthesia was associated with improved survival in open pancreatic cancer surgery compared with desflurane anesthesia. Further investigations are needed to inspect the influences of propofol anesthesia on patient outcomes of pancreatic cancer surgery.

Obesity is a major metabolic disorder driven by excessive adipogenesis and lipid accumulation. This study investigated the anti-obesity effects and molecular mechanisms of Antrodia cinnamomea alcohol extract (ACE) in 3T3-L1 preadipocytes and a high-fat diet (HFD)-induced obesity mouse model. In vitro, Antrodia cinnamomea alcohol extract significantly inhibited adipocyte differentiation and lipid accumulation in 3T3-L1 cells by downregulating PPARγ and C/EBPα, while activating the AMPK pathway and suppressing MAPK signaling. In vivo, Antrodia cinnamomea alcohol extract administration reduced body weight, adipose tissue mass, and liver lipid accumulation in high-fat diet-fed mice, ameliorating non-alcoholic fatty liver disease (NAFLD) symptoms. Transcriptomic analysis of adipose tissue revealed that Antrodia cinnamomea alcohol extract modulated key gene expression profiles related to fatty acid metabolism and adipogenesis, suppressing lipid synthesis while enhancing β-oxidation. Furthermore, Antrodia cinnamomea alcohol extract rebalanced gut microbiota, increasing beneficial bacterial populations such as Akkermansia and Bifidobacterium, while reducing pro-inflammatory Escherichia-Shigella species. These findings demonstrate that Antrodia cinnamomea alcohol extract exerts multifaceted anti-obesity effects by regulating lipid metabolism, adipogenesis pathways, and gut microbiota composition, highlighting its potential as a natural therapeutic agent for obesity management.

Previous researches have shown that anesthetic techniques may influence the patients' outcomes after cancer surgery. Here, we studied the relationship between the type of anesthetic techniques and patients' outcomes following elective robot-assisted radical prostatectomy. This was a retrospective cohort study of patients who received elective, robot-assisted radical prostatectomy between January 2008 and December 2018. Patients were grouped according to the anesthesia they received, namely desflurane or propofol. A Kaplan-Meier analysis was conducted, and survival curves were presented from the date of surgery to death. Univariable and multivariable Cox regression models were used to compare hazard ratios for death after propensity matching. Subgroup analyses were performed for tumor-node-metastasis stage and disease progression. The primary outcome was overall survival, and the secondary outcome was postoperative biochemical recurrence. A total of 365 patients (24 deaths, 7.0%) under desflurane anesthesia, and 266 patients (2 deaths, 1.0%) under propofol anesthesia were included. The all-cause mortality rate was significantly lower in the propofol anesthesia than in the desflurane anesthesia during follow-up (P = 0.001). Two hundred sixty-four patients remained in each group after propensity matching. The propofol anesthesia was associated with improved overall survival (hazard ratio, 0.11; 95% confidence interval, 0.03-0.48; P = 0.003) in the matched analysis. Subgroup analyses showed that patients under propofol anesthesia had less postoperative biochemical recurrence than those under desflurane (hazard ratio, 0.20; 95% confidence interval, 0.05-0.91; P = 0.038) in the matched analysis. Propofol anesthesia was associated with improved overall survival in robot-assisted radical prostatectomy compared with desflurane anesthesia. In addition, patients under propofol anesthesia had less postoperative biochemical recurrence.

Background Pelvic fracture with hypovolemic shock is a known crucial injury in trauma patients. Pelvic fracture with vessel injury often leads to hemodynamic complications; in a trauma scenario, evidence of other systems being affected is often absent. Bleeding cessation and resuscitation are important for these types of trauma patients. For this purpose, pelvic angiographic embolization is frequently used. Multiple studies have reported that angiographic embolization may cause erectile dysfunction (ED) in hemodynamically stable patients with pelvic fracture. However, no study has evaluated a large patient cohort with a long-term follow-up. We hypothesized that angiographic embolization to control bleeding may compromise blood supply to the genitourinary organs or cause secondary neurogenic injury that increases the risk of ED. Our goal was to evaluate the risk of ED following pelvic fractures in male patients treated with pelvic angiographic embolization. Methods We used data from the National Health Insurance Research Database (NHIRD) from 1997 to 2010 provided by the Bureau of National Health Insurance of the Department of Health in Taiwan. We collected disease histories from inpatient files. The disease diagnoses were based on the International Classification of Diseases (ICD), Ninth Revision, Clinical Modification. These data were all deidentified, and we did not contact the patients. As such, informed consent was not needed. Results Eighty-five and 82,802 patients were included in the case and control cohorts, respectively. All patients were aged 15–45, and the proportion of pelvic fracture locations was equal between the groups. After investigating the causes of ED among male patients aged 15–45 with pelvic fractures using logistic regression analysis in a generalized estimating equations model and after adjusting for the influence of confounders, we found that these patients had high risks (odds ratio (OR): 32.637; 95% confidence interval: 14.137–75.346; P < 0.001) of developing ED post-angiographic embolization. Conclusions Male patients in Taiwan with pelvic fractures who undergo angiographic embolization to control bleeding have a higher risk of ED than those who do not undergo the procedure. Physicians should practice caution and inform patients of this connection before the procedure.

Two new ubiquinones, named antrocinnamone and 4-acetylantrocamol LT3, were isolated along with six known ubiquinones from Antrodia cinnamomea (Polyporaceae) mycelium. The developed HPLC analysis methods successfully identified eight different ubiquinones, two benzenoids, and one maleic acid derivative from A. cinnamomea. The ubiquinones 1–8 exhibited potential and selective cytotoxic activity against three human cancer cell lines, with IC50 values ranging from 0.001 to 35.883 μM. We suggest that the different cytotoxicity levels were related to their chemical structures, especially the 4-hydroxycyclohex-2-enone ring and the presence of a free hydroxyl group in the side chain. The suppression by 4-acetylantrocamol LT3 stopped the cell cycle at the beginning of the G2-M phase thus making the cell cycle arrest at the sub-G1 phase as compared with control cells.

Pelvic angiographic embolization is an effective procedure to provide haemostasis in patients with pelvic fractures. However, management with repeated follow-up radiographs may result in infertility. The study aimed to evaluate the risk of infertility following pelvic fracture treated with pelvic angiographic embolization in female patients. We used data from the National Health Insurance Research Database (NHIRD) provided by the Bureau of National Health Insurance of the Department of Health in Taiwan from the period of 1997-2010. A total of 36 and 18,029 patients were included in the case and control cohorts, respectively. The risk estimations for the case and control cohorts were compared using a Cox's proportional hazards regression model. The significance level was set at <0.05. After adjusting for possible confounding factors, the incidence of infertility in the case cohort was nearly 30.7-fold higher than that in the control cohort (adjust hazard ratio [HR] = 30.7, 95% confidence interval [CI] = 10.643-70.109). Patients between 15-35 years of age had a much higher incidence of infertility in the case cohort than in the control cohort (adjusted HR = 49.9, 95% CI = 15.177-64.099). Taken together, pelvic fractures in female patients treated with arterioembolization for haemostasis might be associated with a higher risk of infertility in Taiwan. Physicians should be aware of the link and inform patients of this risk prior to arterioembolization.

We investigated whether lower urinary tract infection (LUTI), including cystitis or urethritis, is associated with an increased risk of developing prostate cancer (PCa), in a nationwide population-based cohort study. We identified 14,273 men newly diagnosed with LUTI (9347 with cystitis, and 4926 with urethritis) between 1998 and 2011, from the Taiwan Longitudinal Health Insurance Database 2000. Each patient was randomly frequency-matched with 4 men without LUTI, based on age and index year of diagnosis. Cox's proportional hazard regression analysis was performed to estimate the effect of LUTI on the PCa risk. The risk of developing PCa was significantly higher in the cystitis cohort (adjusted HR = 1.46, 95% CI = 1.20-1.78) and in the urethritis cohort (adjusted HR = 1.72, 95% CI = 1.26-2.34) than in the group without LUTI. Further analyses indicated that patients with more than 5 medical visits for LUTI per year had a significantly greater risk of developing PCa. We found that cystitis or urethritis may play an etiological role in the development of PCa in Taiwanese men, particularly in those with repeated medical visits for cystitis or urethritis. Further studies are warranted on the association between LUTI and PCa in other countries, particularly where the prevalence of PCa is high.

To investigate if dose escalation using intracavitary brachytherapy (ICBT) improves local control for nasopharyngeal carcinoma (NPC) in the era of intensity-modulated radiation therapy (IMRT) and concurrent chemoradiation treatment (CCRT). We retrospectively analyzed 232 patients with Stage T1–3 N0–3 M0 NPC who underwent definitive IMRT with or without additional ICBT boost between 2002 and 2013. For most of the 124 patients who had ICBT boost, the additional brachytherapy was given as 6 Gy in 2 fractions completed within 1 week after IMRT of 70 Gy. CCRT with or without adjuvant chemotherapy was used for 176 patients, including 88 with and 88 without ICBT boost, respectively. The mean follow-up time was 63.1 months. The 5-year overall survival and local control rates were 81.5% and 91.5%, respectively. ICBT was not associated with local control prediction (P = 0.228). However, in a subgroup analysis, 75 T1 patients with ICBT boost had significantly better local control than the other 71 T1 patients without ICBT boost (98.1% vs 85.9%, P = 0.020), despite having fewer patients who had undergone chemotherapy (60.0% vs 76.1%, P = 0.038). Multivariate analysis showed that both ICBT (P = 0.029) and chemotherapy (P = 0.047) influenced local control for T1 patients. Our study demonstrated that dose escalation with ICBT can improve local control of the primary tumor for NPC patients with T1 disease treated with IMRT, even without chemotherapy.

Background To analyze the rate of larynx preservation in patients of locally advanced hypopharyngeal cancer treated with intensity modulated radiotherapy (IMRT) plus concurrent chemotherapy, and compare the results with patients treated with primary surgery. Methods Between January 2003 and November 2007, 14 patients were treated with primary surgery and 33 patients were treated with concurrent chemoradiotherapy (CCRT) using IMRT technique. Survival rate, larynx preservation rate were calculated with the Kaplan-Meier method. Multivariate analysis was conducted for significant prognostic factors with Cox-regression method. Results The median follow-up was 19.4 months for all patients, and 25.8 months for those alive. The 5-year overall survival rate was 33% and 44% for primary surgery and definitive CCRT, respectively (p = 0.788). The 5-year functional larynx-preservation survival after IMRT was 40%. Acute toxicities were common, but usually tolerable. The rates of treatment-related mucositis (≥ grade 2) and pharyngitis (≥ grade 3) were higher in the CCRT group. For multivariate analysis, treatment response and cricoid cartilage invasion strongly correlated with survival. Conclusions IMRT plus concurrent chemotherapy may preserve the larynx without compromising survival. Further studies on new effective therapeutic agents are essential.

The locoregional failure rate remains high after concurrent chemoradiotherapy with standard-dose radiotherapy (RT, 50–50.4 Gy) for oesophageal cancer (EC). This retrospective study evaluated whether RT dose escalation was effective among 115 consecutive patients with non-metastatic EC (July 2003 to November 2016). Forty-four patients received an RT dose of <66 Gy and 71 patients received ≥66 Gy, with most patients receiving concurrent cisplatin plus fluorouracil. The median follow-up was 12 months for all patients (52 months for 18 surviving patients). The ≥66 Gy group had significantly higher 3-year rates of overall survival (17.9% vs. 32.1%, p = 0.026) and local progression-free survival (46.1% vs. 72.1%, p = 0.005), but not disease progression-free survival (11.4% vs. 21.9%, p = 0.059) and distant metastasis-free survival (49% vs. 52.6%, p = 0.852). The ≥66 Gy group also had significantly better 5-year overall survival compared with 41.4–65.9 Gy. The only significant difference in treatment-related toxicities involved acute dermatitis (7% vs. 28%, p = 0.009). Inferior overall survival was associated with poor performance status, clinical N2–3 stage and not receiving maintenance chemotherapy. In conclusion, patients with inoperable EC experienced better survival outcomes and acceptable toxicities if they received higher dose RT (≥66 Gy) rather than lower dose RT (<66 Gy).
