背景与目的 对卫生保健干预措施进行决策权衡需要有不良和有益的可靠证据,然而绝大多数系统评价针对的是研究方法非常成熟的随机对照试验及其有效性评价,系统地评价不良反应的方法尚未完善,对研究者而言,能作为相关指南的资源很少.为此,作者在文中报告了对不良反应进行系统评价的新近体会,同时提出进一步实践和研究的建议.方法 描述并比较3个包含不良反应评价的药物干预的系统评价的方法学,重点评价其研究问题、研究设计和质量评价.结果 1个研究关注于如何根据提供的特殊不良反应数据建立卫生经济学模式,而其它两个研究涉及更广泛的问题.尽管每个评价对纳入标准的定义不同,但它们均纳入了随机和观察性数据.对研究质量的评价采用了标准方法.由于研究设计不良、报告不充分和现有研究工具有限,在运用纳入标准和评估研究质量时,研究者遇到了各种问题.最终发现,3个评价都做了大量的工作,但对卫生保健决策者有用的资料不多.研究者确认,改善的关键在于如何提出系统评价的问题和发展不良反应研究的质量评价方法学.结论 若不良反应的系统评价只专注于一个中心问题,那么它会提供与临床决策更相关的资料,也有利于明确纳入系统评价研究的类型.系统评价中不良反应的质量评估的方法学需要进一步完善.
Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic at the end of December 2019, more than 85% of the population in China has been infected. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mainly affects the respiratory system, especially the lungs. The mortality rate of patients with severe infection is high. A percentage of 6% to 10% of patients will eventually develop into COVID-related acute respiratory distress syndrome (CARDS), which requires mechanical ventilation and extracorporeal membrane oxygenation (ECMO) support. Some patients who survive acute lung injury will subsequently develop post COVID-19 pulmonary fibrosis (PCPF). Both fully treated CARDS and severe PCPF are suitable candidates for lung transplantation. Due to the special course, evaluation strategies are different from those used in patients with common end-stage lung disease. After lung transplantation in COVID-19 patients, special treatment is required, including standardized nucleic acid testing for the novel coronavirus, adjustment strategy of immunosuppressive drugs, and rational use of antiviral drugs, which is a big challenge for the postoperative management of lung transplantation. This consensus was evidence-based written and was reached by experts after multiple rounds of discussions, providing reference for assessment and postoperative management of patients with interstitial pneumonia after COVID-19 infection.
This paper proposes algorithm in predicting the RNA secondary structure that combines several sequence comparisons, searches the eigenvalue for subsequence division with dynamic programing, utilizing the minimum free energy method. Moreover, the paper assesses the results derived from this new algorithm based on base-pairs distance, climbing distance and morphology distance. The paper also compares the assessment result and the prediction results of different prediction tools, and analyzes the advantages of the new method and its improvement direction.
ObjectiveTo systematically evaluate the measurement properties of observational pain assessment scales for pediatric patients after surgery. MethodsThe PubMed, Embase, CINAHL, PsycArticles, and SinoMed databases were electronically searched to collect studies related to the objects from inception to April 13, 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. And the quality of measurement properties was rated using updated criteria for good measurement properties to determine recommendation levels. ResultsA total of 26 studies were finally included involving 12 observational pain assessment scales for pediatric patients after surgery. None reported measurement error or cross-cultural validity. The overall content validity of all 12 scales was evaluated by reviewers, with measurement properties rated as sufficient or inconsistent. For internal consistency, due to insufficient or uncertain content validity, the evidence quality was low. Eight scales calculated internal consistency, among which CHEOPS, CHIPPS, COMFORT, FLACC, and NCCPC-PV scales had sufficient measurement properties with evidence quality of low or above, receiving Grade A recommendations. ConclusionCompared with other scales, CHEOPS, CHIPPS, COMFORT, FLACC, and NCCPC-PV scales demonstrated good measurement property evaluation with acceptable evidence quality and can be recommended for use. Other scales still require further improvement in measurement property validation.
Objective To explore the characteristics of cognitive impairment in patients with alcohol dependence, and analyze the related influencing factors. Methods The Montreal Cognitive Assessment Scale (MoCA) was used to evaluate the cognitive function of 65 alcohol dependent patients hospitalized between January 1st and December 31st, 2014. The features of cognitive impairment and related influencing factors were analyzed. Results The differences of MoCA attention and delayed recall between different drinking year groups had statistical significance (P<0.05). The correlations of drinking year with MoCA attention (r=–0.250,P=0.044), and with delayed recall (r=–0.326,P=0.008) were both negative. MoCA scores, naming, attention and delayed recall were different statistically among different age groups (P<0.05). The correlations of ages with MoCA scores (r=–0.429,P<0.001), naming (r=–0.261,P=0.035), attention (r=–0.391,P=0.001) and delayed recall (r=–0.461,P<0.001) were all negative. MoCA scores, the visuoconstructional skills, language, abstraction and delayed recall were significantly different among different education level groups (P<0.05). The correlations of education level with MoCA scores (rs=0.650,P<0.001), the visuoconstructional skills (rs=0.540,P<0.001), language (rs=0.486,P<0.001), abstraction (r=0.602,P<0.001) and delayed recall (rs=0.593,P<0.001) were all positive. Ages had an effect on MoCA scores by multiple linear regression analysis (P<0.01). Conclusions For alcohol dependent patients with cognitive impairment, cognitive function is correlated with drinking year, age and education level. The cognitive function is much serious in patients with older age and longer drinking years. This kind of patients should be focused on and intervened early.
Frailty is a syndrome characterized by vulnerability to stressors due to loss of physiological reserve. In recent years, many researches have confirmed that frailty is a risk factor for postoperative complications of cardiac surgery, such as readmission, adverse cardiovascular events, and death in elderly patients. This paper reviews the concept of frailty, the relationship between frailty and cardiac surgery, the frailty assessment and intervention strategy in perioperative period, aimed at providing decision making basis for the risk stratification and perioperative management of cardiac surgery in elderly patients.
目的 探讨功能性排便障碍人群心理评估中心理和情绪的变化。方法 采用SCL-90、SAS和SDS量表对72例功能性排便障碍患者进行心理评估并分析结果。结果 便秘组SCL-90测试的总分以及躯体化、抑郁、焦虑及精神病性这4项因子的评分结果均高于对照组(P<0.001),2组其余各因子的评分结果差异没有统计学意义(P>0.05)。便秘组SAS和SDS测试的评分结果均高于对照组,表明便秘组焦虑和抑郁的评分均较对照组高(P<0.001)。结论 功能性便秘患者不同程度伴随有情绪和情感的异常,因此对该部分患者进行药物干预的同时给予其心理辅导是非常有必要的。
