Background Bone metastases-induced skeletal complications result in reduced patient survival, lower quality of life, and an increase in healthcare costs. Previously, zoledronic acid (ZA) was the standard choice of treatment for bone metastases, but another drug, denosumab, has also shown promise. However, the clinical utility of these two drugs requires further exploration. Aim of the review Due to the lack of direct comparisons regarding the efficacy of these drugs in both solid tumors and multiple myeloma (MM), we herein tried to conduct a meta-analysis to compare their efficacy in parallel for bone metastases treatment in both solid tumor and MM patients. Methods Multiple databases including Cochrane Library, MEDLINE, EMBASE, and Web of Science were searched to identify randomized controlled trials (RCTs) reported up to March 2019 directly comparing denosumab with ZA in solid tumors and MM. Information about the following events was primarily searched time to first on-study skeletal-related event (SRE), time to first and subsequent SREs, and overall survival. Information about secondary outcomes including disease progression, pain, health-related quality of life, and adverse events was also recorded. Results Overall, we analyzed data from four distinct RCTs including 7441 patients, and our analysis revealed that patients in the denosumab group had a significantly delayed incidence to the first and subsequent SREs. In addition, denosumab resulted in a higher incidence of hypocalcemia and osteonecrosis of the jaw (ONJ), and a lower incidence of renal toxicity and acute phase reactions, in comparison to ZA. Conclusion Overall, denosumab showed superiority in delaying the first and subsequent SREs, and hence seems to be a promising choice for managing bone metastases in both solid tumors and MM. However, it can induce a higher incidence of ONJ and hypocalcaemia, but these are preventable and manageable effects.High-dose biotin (HDB) is a therapy used in non-active progressive multiple sclerosis (PMS). Several reports have suggested that HDB treatment may be associated with an increased risk of relapse. We aimed to determine whether HDB increases the risk of clinical relapse in PMS and describe the characteristics of the patients who experience it. We conducted a French, multicenter, retrospective study, comparing a group of PMS patients treated with HDB to a matched control group. Poisson regression was applied to model the specific statistical distribution of the annualized relapse rate (ARR). A propensity score (PS), based on the inverse probability of treatment weighting (IPTW), was used to adjust for indication bias and included the following variables gender, primary PMS or not, age, EDSS, time since the last relapse, and co-prescription of a DMT. Two thousand six hundred twenty-eight patients treated with HDB and 654 controls were analyzed with a follow-up of 17 ± 8 months. Among them, 148 validated relapses were observed in the group treated with biotin and 38 in the control group (p = 0.62). After adjustment based on the PS, the ARR was 0.044 ± 0.23 for the biotin-treated group and 0.028 ± 0.16 for the control group (p = 0.18). The more relapses there were before biotin, the higher the risk of relapse during treatment, independently from the use of HDB. While the number of relapses reported for patients with no previous inflammatory activity receiving biotin has gradually increased, the present retrospective study is adequately powered to exclude an elevated risk of relapse for patients with PMS treated with HDB.
  Urinary incontinence (UI) and low quality of life (QoL) are two common conditions. Some recent literature proposed that these two entities can be associated. However, no attempt was made to collate this literature.  https://www.selleckchem.com/products/AZD2281(Olaparib).html  Therefore, the aim of this study was to conduct a systematic review and meta-analysis of existing data to estimate the strength of the association between UI and QoL.
 
  An electronic search of major databases up to 18th April 2020 was carried out. Meta-analysis of cross-sectional and case-control studies comparing mean values inQoL between patients with UI and controls was performed, reporting random-effects standardized mean differences (SMDs) ± 95% confidence intervals (CIs) as the effect size. Heterogeneity was assessed with the I
  .
 
  Out of 8279articles initially screened, 23 were finally included for a total of 24,983 participants, mainly women. The mean age was ≥ 50years in 12/23 studies. UI was significantly associated with poor QoL as assessed by the short-form 36 (SF-36) total score (n = 6 studies; UI 473 vs. 2971 controls; SMD = - 0.89; 95% CI - 1.3 to - 0.42; I
   = 93.5) and by the sub-scales of SF-36 and 5/8 of the domains included in the SF-36. Similar results were found using other QoL tools. The risk of bias of the studies included was generally high.
 
  UI is associated with a poor QoL, with a strong level of certainty. This work, however, mainly based on cross-sectional and case-control studies, highlights the necessity of future longitudinal studies for better understanding the importance of UI on QoL.

PACAP binds with high affinity to PAC1, which causes transactivation of receptor tyrosine kinases (RTK) for the EGFR and HER2 but its effect on HER3 is unknown. Using 3 NSCLC cell lines (NCI-H358, NCI-H441, and Calu-3), proteins for EGFR, HER2, HER3, and PAC1 were detected. The increase in EGFR tyrosine phosphorylation caused by PACAP was blocked by the EGFR tyrosine kinase inhibitor (TKI) gefitinib, or PACAP(6-38), a PAC1 antagonist. The increase in HER2 tyrosine phosphorylation caused by PACAP was inhibited by trastuzumab, a monoclonal antibody (mAb) for HER2, or PACAP(6-38). The increase in HER3 tyrosine phosphorylation caused by PACAP was inhibited by HER3 mAb3481 or PACAP(6-38). Immunoprecipitation experiments indicated the PACAP addition to Calu-3 cells resulted in the formation of EGFR/HER3 and HER2/HER3 heterodimers. Addition of the HER3 agonist neuregulin (NRG)-1 increased HER3 tyrosine phosphorylation in non-small-cell lung cancer (NSCLC) cells.
