PurposeUnderstanding the value of genetic screening and testing for monogenic disorders requires high-quality, methodologically robust economic evaluations. This systematic review sought to assess the methodological quality among such studies and examined opportunities for improvement.MethodsWe searched PubMed, Cochrane, Embase, and Web of Science for economic evaluations of genetic screening/testing (2013-2019). Methodological rigor and adherence to best practices were systematically assessed using the British Medical Journal checklist.ResultsAcross the 47 identified studies, there were substantial variations in modeling approaches, reporting detail, and sophistication. Models ranged from simple decision trees to individual-level microsimulations that compared between 2 and >20 alternative interventions. Many studies failed to report sufficient detail to enable replication or did not justify modeling assumptions, especially for costing methods and utility values. Meta-analyses, systematic reviews, or calibration were rarely used to derive parameter estimates. Nearly all studies conducted some sensitivity analysis, and more sophisticated studies implemented probabilistic sensitivity/uncertainty analysis, threshold analysis, and value of information analysis.ConclusionWe describe a heterogeneous body of work and present recommendations and exemplar studies across the methodological domains of (1) perspective, scope, and parameter selection; (2) use of uncertainty/sensitivity analyses; and (3) reporting transparency for improvement in the economic evaluation of genetic screening/testing. 相似文献
目的探究辛伐他汀联合二甲双胍治疗糖尿病胰岛素抵抗的疗效。方法选取2019年3月至2020年3月本院收治的92例糖尿病胰岛素抵抗患者作为研究对象,随机分为对照组与实验组,各46例,对照组单独应用二甲双胍治疗,实验组联合应用辛伐他汀、二甲双胍进行治疗,比较两组疗效。结果实验组治疗总有效率高于对照组(P<0.05);治疗后,实验组TC、LDL-C、FPG、2 h PG均低于对照组,HDL-C高于对照组(P<0.05);治疗后2、8、12周,实验组TC、LDL-C、FPG、2 h PG逐渐降低、HDL-C逐渐升高(P<0.05);对照组TC、LDL-C、FPG、2 h PG无明显变化,差异无统计学意义;两组不良反应发生率比较差异无统计学意义。结论辛伐他汀联合二甲双胍治疗糖尿病胰岛素抵抗疗效高于单一治疗方案,且药物联用未增加不良反应风险,疗效显著,安全性高,值得临床推广应用。 相似文献
The exercise pressor reflex is a feedback mechanism engaged upon stimulation of mechano- and metabosensitive skeletal muscle afferents. Activation of these afferents elicits a reflex increase in heart rate, blood pressure, and ventilation in an intensity-dependent manner. Consequently, the exercise pressor reflex has been postulated to be one of the principal mediators of the cardiorespiratory responses to exercise. In this updated review, we will discuss classical and recent advancements in our understating of the exercise pressor reflex function in both human and animal models. Particular attention will be paid to the afferent mechanisms and pathways involved during its activation, its effects on different target organs, its potential role in the abnormal cardiovascular response to exercise in diseased states, and the impact of age and biological sex on these responses. Finally, we will highlight some unanswered questions in the literature that may inspire future investigations in the field.
