Title: Machine Learning–Driven Prediction of Risk Factors for Postoperative Deep Vein Thrombosis in Geriatric Patients Undergoing Hip Fracture Surgery
Abstract:
Geriatric populations exhibit heightened vulnerability to fragility fractures—a prevalent type of low-energy injury resulting from minimal trauma, such as a ground-level fall. These fractures represent a major public health concern, with their increasing incidence paralleling global demographic shifts toward an aging society. This trend not only exacerbates pressures on healthcare infrastructure but also challenges socioeconomic stability. Beyond acute morbidity, hip fractures profoundly impair functional independence and quality of life, while imposing considerable economic and caregiving burdens on healthcare systems.
理由:
-
标点与连字符规范:
- “Machine Learning-Driven” → “Machine Learning–Driven”:复合形容词作前置定语时,若首词为开放型复合词(如 Machine Learning,含空格),应使用en dash(–)而非hyphen(-)连接,符合《Chicago Manual of Style》及主流学术期刊(如Nature、JAMA)的排版惯例。
-
冗余修饰词删减:
- “a heightened vulnerability” → “heightened vulnerability”:冠词“a”与不可数抽象名词“vulnerability”搭配不当(vulnerability 为不可数名词,泛指时无需冠词);且“heightened”本身已含程度义,“a”不仅语法错误,更削弱学术表达的简洁性。
-
用词准确性与术语规范:
- “a prevalent category of low-energy injuries” → “a prevalent type of low-energy injury”:
• “category” 暗示人为划分的层级类目(如ICD分类),而此处强调临床共性特征,type 更准确;
• “injuries” 应为单数injury ,因“low-energy injury”是医学固定术语(如“low-energy injury pattern”),且其后同位语“such as a ground-level fall”为单数实例,需保持数的一致性。
- “a prevalent category of low-energy injuries” → “a prevalent type of low-energy injury”:
-
动词精准性与学术惯用语:
- “stemming from” → “resulting from”:在描述病因/机制时,“resulting from” 更常用于医学文献(PubMed高频搭配),语义更中性客观;“stemming from” 偏口语化,且隐含“起源”意味,易引发歧义(如误指生物学起源而非诱因)。
-
逻辑衔接与搭配优化:
- “escalating incidence” → “increasing incidence”:
• “escalating” 多用于负面事态的失控性加剧(如 escalating conflict, escalating costs),含强烈贬义和紧迫感;
• “incidence” 是中性流行病学指标,用increasing (客观描述趋势)更符合学术语境,避免情感色彩干扰。
- “escalating incidence” → “increasing incidence”:
-
名词单复数与搭配修正:
- “healthcare infrastructures” → “healthcare infrastructure”:
• “infrastructure” 为不可数集合名词(指整体系统能力),无复数形式;
• “infrastructures” 属常见错误,多见于非母语作者,须修正为infrastructure 。
- “healthcare infrastructures” → “healthcare infrastructure”:
-
动词语义强化与临床准确性:
- “diminish functional independence” → “impair functional independence”:
• “impair” 是康复医学与老年病学标准术语(如 impairment 在WHO ICF框架中特指功能缺失),精准对应临床评估维度;
• “diminish” 语义过宽(可指数量减少、重要性降低等),无法准确传达“生理功能受损”的医学内涵,故替换为impair 。
- “diminish functional independence” → “impair functional independence”:
-
句末截断补全:
- 原文以“healthcare systems an”强行中断,属明显输入错误。根据上下文逻辑及学术摘要惯例,此处应为完整名词短语,故补全为“healthcare systems.”(句号结束),并确保前文所有修饰关系闭合。
注:未修正部分(如标题大小写)已按APA第7版规范统一为标题式大写(实词首字母大写),但因题目本身无语法错误,未使用
