简介:AbstractBackground:The prevalence rates of freezing of gait (FOG) in Parkinson’s disease (PD) vary widely, ranging from 14.0 to 55.1%. Our aim is to calculate the overall prevalence of FOG in all PD patients with different disease durations and severities.Methods:Using Medline/PubMed/Embase, we carried out a systematic literature search for studies reporting the PD and clinically relevant FOG.Results:After primary screening, a total of 35 studies were identified and further analyzed for inclusion into the analysis, and 29 studies fulfilled the quality criteria and included in this meta-analysis. The overall prevalence of FOG in PD was 39.9% (95% CI 35.3-44.5%). The FOG identified by the freezing of gait questionnaire item 3 may be more prevalent (43.8%, 95% CI 38.5-49.1%) than the FOG identified by the Unified Parkinson’s Disease Rating Scale item 14 (36.0%, 95% CI 29.0-43.1%). Disease duration and severity are both the clinical features associated with the FOG. The highest FOG prevalence rate in PD patients was seen in patients with disease durations ≥ 10 years, at 70.8%, followed that of PD patients with disease durations ≥ 5 years (53.3%), and PD patients with disease durations < 5 years (22.4%). FOG presented in 28.4% of PD patients with Hoehn and Yahr staging (H&Y) score ≤ 2.5, and in 68.4% of PD patients with H&Y score ≥ 2.5.Conclusion:This meta-analysis confirms that the prevalence of FOG in PD is considerable, and highlights the need for accurate identification of FOG in PD.

简介:AbstractGastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasm of the digestive system and are not sensitive to traditional chemotherapy. Therefore, historically, surgical resection was the only effective therapy. However, the emergence of tyrosine kinase inhibitors (TKIs) has revolutionized the treatment of GISTs, because they target c-Kit and PDGF receptor-α (PDGFRA), which are important in GIST development and progression. As research into c-Kit and PDGFRA continues, an increasing number of different TKIs are being used in the clinical setting. This review aims to discuss the current state of chemotherapy for the treatment of GISTs with different genotypes.
