BACKGROUND The aim of this study was to review the efficacy and safety of intra-articular (IA) viscosupplementation (VS) for hip osteoarthritis (OA). MATERIAL AND METHODS We searched Medline, Clinical Trial Register Center, EMBASE, and Cochrane databases for randomized controlled trials (RCTs) comparing VS with placebo injection for hip OA. We included suitable studies, assessed the quality of studies, and extracted data on pain reduction, function improvement at different time points, and safety profiles. The comparisons of pain and function outcome were performed by meta-analysis. RESULTS Five high-quality randomized controlled studies trials (RCTs) with 591 patients with hip OA were identified. Although several trials demonstrated a significant decline in pain in VS groups during follow-up compared to baseline, without severe adverse events, the pooled analysis did not show VS was superior to placebo at any time windows [7-14 days: standardized mean difference (SMD): -0.18; 95% CI, -0.47 to 0.10, p=0.21; 28-30 days: 0.02 (-0.15, 0.19), p=0.82; or at final visit: -0.14 (-0.46, 0.18), p=0.38]. Similar results were also observed in the combined data of functional results. CONCLUSIONS IA VS does not reduce pain or improve function significantly better than placebo in a short-term follow-up. The benefits and safety of VS should be further assessed by sufficiently-sized, methodologically sound studies with validated assessment of more clinically relevant end-points.
背景 本研究旨在回顾关节内粘弹性补充剂 (VS) 治疗髋关节骨关节炎 (OA) 的有效性和安全性。材料与方法 我们检索了 Medline、临床试验注册中心、EMBASE 和 Cochrane 数据库，以查找比较 VS 与安慰剂注射治疗髋关节 OA 的随机对照试验 (RCT)。我们纳入了合适的研究，评估了研究质量，并提取了有关疼痛减轻、不同时间点的功能改善和安全性的数据。通过荟萃分析对疼痛和功能结果进行比较。结果 发现了五项高质量的随机对照研究（RCT），共涉及 591 名髋关节 OA 患者。虽然有几项试验表明，与基线相比，VS 组患者在随访期间疼痛明显减轻，且无严重不良反应，但汇总分析结果显示，VS 在任何时间窗均未优于安慰剂[7-14 天：标准化平均差（SMD）：-0.18；95% CI，-0.47 至 0.10，P=0.21；28-30 天：-0.02（-0.15）至 0.10，P=0.21；28-30 天：-0.02（-0.15）至 0.10，P=0.21]：0.02（-0.15，0.19），P=0.82；或在最后一次就诊时：-0.14 (-0.46, 0.18), p=0.38].在功能结果的综合数据中也观察到了类似的结果。结论 在短期随访中，IA VS 减轻疼痛或改善功能的效果并不明显优于安慰剂。VS的益处和安全性应通过规模足够大、方法可靠的研究进行进一步评估，并对更多临床相关终点进行有效评估。

This article is devoted to analyze some ambiguities coming from a class of sediment transport models. The models under consideration are governed by the coupling between the shallow-water and the Exner equations. Since the PDE system turns out to be an hyperbolic system in non conservative form, ambiguities may occur as soon as the solution contains shock waves. To enforce a unique definition of the discontinuous solutions, we adopt the path-theory introduced by Dal Maso, LeFLoch and Murat. According to the path choices, we exhibit several shock definitions and we prove that a shock with a constant propagation speed and a given left state may connect an arbitrary right state. As a consequence, additional assumptions (coming from physical considerations or other arguments) must be chosen to enforce a unique definition. Moreover, we show that numerical ambiguities may still exist even when such a choice is made.
