Prostate cancer is a prevalent malignant tumor of the male genitourinary system in China, with a persistently elevated incidence rate.Given the insidious onset, propensity for metastasis in advanced stages, and poor efficacy of traditional treatments, new hormone therapies have garnered increasing attention in recent years.A number of clinical studies have demonstrated that second-generation androgen receptor inhibitors (SGARIs), including enzalutamide, apalutamide, darolutamide, and rezvilutamide, can be beneficial in different stages of advanced prostate cancer.Furthermore, their early application has been shown to delay disease progression while maintaining a controlled safety profile.At present, SGARIs have increasingly become the primary therapeutic agents for advanced prostate cancer in various stages.This article reviews the clinical research progress of SGARIs in recent years, with the aim of offering valuable clinical reference for clinicians.

OBJECTIVE To investigate the clinical characteristics of euglycemic diabetic ketoacidosis （euDKA） induced by empagliflozin， and provide references for safe medication. METHODS Case reports of euDKA induced by empagliflozin were retrieved and analyzed from PubMed， Web of Science， CNKI， and Wanfang Data. The Naranjo’s scale was adopted to assess the causal relationship between empagliflozin and euDKA. RESULTS A total of 29 patients were enrolled， including 16 males and 13 females，with a median age of 58 years. All patients were diagnosed with type 2 diabetes mellitus； 22 patients had at least one comorbidity. The median time to euDKA onset was 60 days after administration， and 7 cases occurred within 2 weeks of treatment. Perioperative periods，fasting，and low-carbohydrate or ketogenic diets were the main predisposing factors. Common presentations included nausea，vomiting， fatigue， tachypnea，and tachycardia. The causal relationship between empagliflozin and euDKA was assessed as “probable” in all cases. According to adverse reaction severity grading， 13 cases were grade 3 （severe） and 16 cases were grade 4 （life-threatening）. All patients discontinued empagliflozin and recovered after corresponding treatment. CONCLUSIONS euDKA is a serious adverse reaction to empagliflozin， which mostly occurs early in treatment. Perioperative periods， fasting， and ketogenic diets are prone to induce euDKA. Elderly patients and those with comorbidities are at higher risk. Risk assessment should be conducted before clinical administration； blood ketones and acid-base monitoring should be strengthened in the early medication period； withhold the drug before elective surgery， avoid prolonged fasting；upon diagnosis， discontinue empagliflozin and initiate intravenous insulin， provide fluid resuscitation promptly， and use other treatments to improve patient prognosis.

Background/Aims: Reflux symptoms frequently present in patients diagnosed with functional dyspepsia (FD). This investigation sought to elucidate the contribution of gastroesophageal reflux in the overlap relationship. Methods: Consecutive patients presenting with reflux symptoms and/or FD symptoms were prospectively included. Comprehensive assessments, including symptoms evaluation, endoscopy, esophageal functional examinations (high-resolution manometry and reflux monitoring), and proton pump inhibitor (PPI) treatment efficacy evaluation, were conducted in these patients. Results: The study enrolled 315 patients, 43.2% of which had concurrent FD symptoms and overlapping reflux symptoms. Notably, a mere 28.7% of patients in the overlap symptoms group had objective gastroesophageal reflux disease evidences (the grade of esophagitis≥ B or the acid exposure time ≥ 4.2%). Functional heartburn was demonstrated to be the main cause of overlapping reflux symptoms(55.1%). Reflux parameters analysis revealed that the reflux burden in the overlap symptoms group paralleled that of the FD symptoms group, with both registering lower levels than the reflux symptoms group (P < 0.05). Furthermore, PPI response rates were notably diminished in the overlap symptoms group (P < 0.001), even for those with objective gastroesophageal reflux disease evidences. Conclusions The study illuminated that overlapping reflux symptoms in FD was common. Strikingly, these symptoms primarily diverged from reflux etiology and exhibited suboptimal responses to PPI intervention. These findings challenge prevailing paradigms and accentuate the imperative for nuanced therapeutic approaches tailored to the distinctive characteristics of overlapping reflux symptoms in the context of FD.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

Objective:To explore the effects of age and gender on the sagittal spinal-pelvic parameters during the natural aging process of healthy adults.Methods:A total of 647 Chinese healthy adults who underwent health check-ups at the Second Affiliated Hospital of Zhejiang University School of Medicine and Songyang County People's Hospital, from January 2017 to September 2024 were collected. There were 277 males and 370 females, aged 18-93 years. Anteroposterior and lateral X-ray films of the whole spine were taken to evaluate the spinal-pelvic sagittal morphology. The following parameters were measured: thoracic kyphosis (TK), lumbar lordosis(LL), sacral slope (SS), pelvic incidence (PI), pelvic tilt (PT), global tilt (GT), T 1-pelvic angle (TPA), sagittal vertical axis (SVA), thoracic Cobb angle (T-Cobb), lower end vertebra of thoracic Cobb angle (T-LEV), apex vertebra of thoracic Cobb angle (T-Apex), lumbar Cobb angle (L-Cobb). Compare the differences in spine-pelvis parameters among patients of different genders and age groups (in this study, the subjects were subdivided into the 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-93 years groups according to the age range). Results:The results showed that GT, SVA, TPA, and PT increased with age ( P<0.05). For males aged 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-93 years, PT values were 8.58°±6.47°, 9.60°±5.63°, 12.65°±7.13°, 11.00°±6.99°, 13.01°±8.63°, 15.77°±8.02°, and 18.47°±10.03° respectively; for females in the same age groups, the PT values were 8.44°±6.83°, 9.00°±6.44°, 11.84°±7.35°, 12.07°±7.51°, 15.44°±9.39°, 19.26°±8.28°, and 18.17°±9.43° respectively. For males in these age groups, the global tilt (GT) values were 6.37°±7.20°, 8.77°±6.51°, 10.38°±9.07°, 8.80°±7.49°, 10.80°±8.62°, 16.07°±10.42°, and 21.99°±12.65° respectively; for females, the GT values were 4.46°±8.09°, 5.96°±7.83°, 8.17°±6.88°, 9.41°±8.03°, 9.96°±1.39°, 17.89°±9.39°, and 19.55°±12.34° respectively. The sagittal vertical axis (SVA) values for males in the age groups were -7.94±25.57 mm, -2.98±25.69 mm, -4.63±20.90 mm, -6.43±32.81 mm, 7.85±43.39 mm, 36.49±53.89 mm, and 55.57±51.10 mm respectively; for females, they were -24.12±31.35 mm, -17.49±25.12 mm, -17.88±22.72 mm, -8.25±30.91 mm, 8.80±27.45 mm, 28.67±38.22 mm, and 23.23±35.19 mm respectively. For males, the thoracic pelvic angle (TPA) values across the age groups were 4.46°±5.94°, 6.05°±5.38°, 9.58°±9.35°, 7.52°±7.64°, 11.23°±9.59°, 16.32°±12.38°, and 18.49°±11.70° respectively; for females, the TPA values were 2.72°±6.88°, 3.68°±6.26°, 7.30°±6.11°, 7.44°±6.75°, 12.64°±9.79°, 19.08°±10.39°, and 16.79°±13.19° respectively. T-Cobb, T-LEV, and T-Apex increased slowly with age ( P<0.05). The pelvic incidence (PI) remained relatively constant in males ( P>0.05), while it increased slowly with age in females ( P<0.05). Conclusions:Sagittal anteversion of the spinal-pelvis increases with age. Gender differences are reflected in specific changes in the fluctuation amplitude of certain parameters (such as PI), and the fluctuations of indicators like T-Cobb, T-LEV, and T-Apex are closely related to the natural aging process of the spine.
