This study used National Health and Nutrition Examination Surveys data from 1999 to 2006 to investigate the association between dietary inflammatory potential, represented by dietary inflammatory index (DII) scores, and the risk of sarcopenia in U.S. adults. A total of 25,781 participants were included in the study. The DII scores were calculated based on dietary information collected from 24-hour recalls. Men and women were classified as sarcopenic if appendicular lean mass (ALM) adjusted for BMI (ALMBMI) was <0.789 or <0.512, respectively. The covariates included comorbidities, dietary data, demographic data, and physical examination data. In a full-adjusted model, each unit of increase in DII score was associated with a 12% increase in risk of sarcopenia. When categorizing sarcopenia into tertiles, the adjusted effect size (relative to Tertile1) was 1.26 (95% CI, 1.07, 1.47) for Tertile 2 and 1.55 (95% CI, 1.31, 1.83) for Tertile 3. The trend test showed that the risk of sarcopenia increased with increasing DII tertiles, (P <0.0001). These findings demonstrate that dietary inflammatory potential correlates positively with the risk of sarcopenia and suggest that making ones diet inflammatory may reduce the incidence of sarcopenia and its associated negative health outcomes.

The aim of the study was to systematically review the relevant studies to assess the role of fluorescence in situ hybridization (FISH) test for predicting patient response to Bacillus Calmette–Guérin (BCG) therapy after transurethral resection of bladder tumor (TURBT). We searched PubMed, Embase, and the Cochrane Library from inception to July 5, 2018, and used Quality Assessment Tool for Diagnosis Accuracy Studies (QUADAS-2) to assess the quality. We pooled sensitivity, specificity, and area under curve (AUC) of baseline and post-BCG FISH test for predicting tumor recurrence. Hazard ratio (HR) with 95% confidence intervals (95% CIs) and a Fagan nomogram were applied to assess predictive accuracy of post-BCG FISH test. A total of 6 studies with 442 participants for post-BCG test and 404 participants for baseline BCG test were included. The pooled analysis for post-BCG FISH test revealed the sensitivity of 0.54 (95% CI 0.38–0.69), specificity of 0.84 (95% CI: 0.72–0.91), and area under the curve (AUC) of 0.78 (95% CI: 0.74–0.81) for predicting tumor recurrence. Patients with positive post-BCG FISH test were more likely to recur during follow-up (HR 3.95, 95% CI 2.72–5.72). The Fagan nomogram revealed the “post-test” probability of tumor recurrence increased by 29% for patients with positive post-BCG FISH test. The baseline FISH test had a pooled sensitivity of 0.70 (95% CI 0.55–0.81), specificity of 0.41 (95% CI: 0.26–0.58), and AUC of 0.60 (95% CI: 0.56–0.64) for predicting recurrence. The post-BCG FISH test can predict BCG failure with high specificity and patients with positive post-BCG FISH test were more likely to recur. However, the relatively low sensitivity of post-BCG FISH test and unsatisfactory performance of baseline FISH test may limit their mono-use.

Background: Disitamab vedotin (DV, RC48-ADC) has shown promising efficacy and manageable safety as monotherapy or combined with immune checkpoint inhibitors (ICIs) in metastatic urothelial carcinoma (mUC) patients progressing after systemic chemotherapy. This study evaluates the efficacy and safety of RC48-ADC plus ICIs in metastatic upper tract urothelial carcinoma (mUTUC) in a real-world setting. Methods: This retrospective, multicenter study included 198 mUTUC patients treated with RC48-ADC plus ICI at 23 clinical centers between June 2021 and December 2023. Data were analyzed from July to September 2024. Primary endpoint: objective response rate (ORR). Secondary endpoints: progression-free survival (PFS), overall survival (OS), duration of response (DoR), time to objective response, and treatment-related adverse events (TRAEs). Result: Among the patients, 122 (61.6%) received combination therapy as first-line treatment, while 76 (38.4%) as second-line or beyond. ORR was 58.6% (95% CI: 51.4–65.5), with a median PFS of 13.0 months; median OS was not reached. Subgroup analyses showed consistent ORR across all subgroups. Adverse events (AEs) occurred in 79.8% of patients, with grade 3–4 AEs in 19.7%. Common AEs included neuropathy (40.4%), fatigue (26.8%), alopecia (25.3%), and rash (21.7%). The main limitations of this study include its retrospective design and the population of the study only include patients from China, leading to potential selection bias. Conclusions: RC48-ADC combined with ICIs demonstrated robust antitumor activity and a favorable safety profile in real-world mUTUC, particularly in selected patient groups. Further studies are needed to explore its potential in this high-risk population.

This umbrella review aimed to summarize and provide a general evaluation of the effectiveness of current treatments for male infertility and assess the quality of evidence and possible biases. An umbrella review of systematic reviews and meta-analyses available in PubMed, Web of Science, and Scopus, covering studies published up to October 2023, was conducted. Sperm concentration, morphology, and motility were used as endpoints to evaluate the effectiveness of the treatments. Of 2998 studies, 18 published meta-analyses were extracted, yielding 90 summary effects on sperm concentration (n = 36), sperm morphology (n = 26), and sperm motility (n = 28) on 28 interventions. None of the meta-analyses were classified as having low methodological quality, whereas 12 (66.7%) and 6 (33.3%) had high and moderate quality, respectively. Of the 90 summary effects, none were rated high-evidence quality, whereas 53.3% (n = 48), 25.6% (n = 23), and 21.1% (n = 19) were rated moderate, low, and very low, respectively. Significant improvements in sperm concentration, morphology, and motility were observed with pharmacological interventions (N-acetyl-cysteine, antioxidant therapy, aromatase inhibitors, selective estrogen receptor modulators, hormones, supplements, and alpha-lipoic acid) and nonpharmacological interventions (varicocele repair and redo varicocelectomy). In addition, vitamin supplementation had no significant positive effects on sperm concentration, motility, or morphology. Treatments for male infertility are increasingly diverse; however, the current evidence is poor because of the limited number of patients. Further well-designed studies on single treatment and high-quality meta-analysis of intertreatment comparisons are recommended.

Early detection of prostate cancer (PCa) is crucial for better patient outcomes. However, due to overdiagnosis with the current biopsy strategy, there is a need to improve and refine the biopsy strategy. The aim of this study was to thoroughly evaluate existing biopsy schemes for patients with suspicious lesions. This study conducted a systematic review and network meta-analysis following PRISMA guidelines (from their start until 15 January 2025), evaluating 13 biopsy schemes for detecting PCa in MRI-positive (PIRADS/Likert score 2-5) patients. Data from PubMed, Embase, and Cochrane databases were examined to assess the efficacy of biopsy schemes in detecting clinically significant (csPCa) and clinically insignificant (ciPCa) prostate cancer. This study is registered with PROSPERO (CRD42024551971). The analysis included 211 studies involving 74,113 individuals. When compared with the combination of systematic biopsy (SB, defined as <20 cores) and targeted biopsy (TB, defined as <6 cores) (SB+TB), ipsilateral SB with TB (ips-SB+TB) and saturation TB did not show statistically significant inferior detection rate of csPCa (ips-SB+TB: RR 0.95, 95% CrI 0.88, 1.02; saturation TB: RR 0.96, 95% CrI 0.91, 1.01). Meanwhile, there was no significant difference in csPCa detection rates for saturation SB+TB, SB+saturation TB compared to SB+TB (saturation SB+TB: RR 1.04, 95% CrI 0.98, 1.11; SB+saturation TB: RR 1.14, 95% CrI 0.999, 1.30). TB and SB alone detected significantly less csPCa than SB+TB (TB: RR 0.86, 95% CrI 0.84, 0.88; SB: RR 0.75, 95% CrI 0.73, 0.77). Saturation SB also did not show significant superiority in detecting csPCa. Additionally, saturation TB and ips-SB+TB also decrease the detection of ciPCa. (ips-SB+TB: RR 0.87, 95% CrI 0.72, 1.04; saturation TB: RR 0.76, 95% CrI 0.65, 0.88). The network meta-analysis reveals that saturation SB+TB and SB+saturation TB have no significant difference in csPCa detection between them and SB+TB. Meanwhile, ips-SB+TB and saturation TB are effective biopsy strategies for MRI-positive PCa patients, offering a more targeted approach for detecting csPCa.
