Optimum support properties for protein separations by high-performance size exclusion chromatography

Optimum chromatographic properties of high performance size exclusion chromatography (HPSEC) of proteins, such as resolution, molecular weight accuracy and recovery, are obtained on packings and columns with tailor-made physical and chemical structures, employed at properly adjusted eluent compositions and operation conditions. SEC-theory suggests that a broad molecular weight fractionation range and high linearity of the log-linear calibration plot can be achieved by the use of two packings (10- and 80-nm pore size, characterized by a pore-size distribution (psd) equal to or less than 1 decade and by equal internal column porosity (p)), rather than a single 30- to 50-nm pore-size packing with a wide psd. Favourably high-phase ratios of (p)/(o)/ 1.0 for HPSEC columns were accomplished with a minimum interstitial column porosity (o) and a high value for the internal column porosity (p) (the specific pore volume, nu(p), multiplied by the packing density, varrho(p).) Ligands such as diol, N-acetoxyamino and oligomeric ether with a propyl- or propoxy-spacer bonded to the silica at the highest density appear to provide high mass recovery and bioactivity as well as chemical stability. Such packings, available in 3-5 mum particle size ranges of narrow distribution, packed into columns 6 mm i.d. and 500 mm in length, offer the best compromise with respect to resolution, speed and pressure drop. More careful studies are required to explain the effects of protein conformational changes and interconversions during elution on HPSEC columns.     

单病种护理质量控制在小儿特发性血小板减少性紫癜中的应用

目的 探讨单病种护理质量控制在小儿特发性血小板减少性紫癜中的应用效果。方法 将我院2020年1月—2021年6月收治的60例特发性血小板减少性紫癜患儿按照随机数字表法进行编号和分组,其中单号患儿纳入为对照组(30例),接受传统护理模式;双号为观察组(30例),按照小儿特发性血小板减少性紫癜护理质量控制标准分阶段实施评估,制定护理计划,落实护理措施。比较两组患儿:⑴临床治疗相关指标(治疗有效率、平均住院时间及住院费用);⑵护理水平相关指标(护理质量、护理人员业务能力);⑶护理效果相关指标(护理依从性、健康教育知晓率及护理满意度)。结果 ⑴观察组治疗总有效率为80.00%(24/30)高于对照组53.33%(16/30)(χ2=4.800,P=0.028);观察组住院时间及住院费用少于对照组(P<0.001);⑵观察组护理质量及护理人员业务能力高于对照组(P<0.001);⑶护理后,观察组护理依从性、健康教育知晓率及护理满意度高于对照组(P<0.006～0.010)。结论 实施单病种护理质量控制标准管理,有利于提高患儿临床治疗效果及护理效果,提升护理水平,缩短住院时间及费用。     

Reference Values and Psychometric Properties of the Quality of Life After Traumatic Brain Injury-Overall Scale in Italy,The Netherlands,and the United Kingdom

ObjectivesThe Quality of Life after Brain Injury-Overall Scale (QOLIBRI-OS) is a short screening instrument for assessing disease-specific health-related quality of life (HRQoL) after traumatic brain injury. To date, no reference values are available for the QOLIBRI-OS in general populations. Thus, this study aimed to establish reference values for the QOLIBRI-OS in general population samples from Italy, The Netherlands, and the United Kingdom.MethodsData were collected using an online survey. The total sample comprised 11759 participants, consisting of 3549 Italian, 3564 Dutch, and 4646 British subjects. In this sample, 49% of the total sample did not report any health complaints, whereas 51% had at least 1 chronic health condition. Reference values were deduced for the QOLIBRI-OS for health-condition–related samples and total general population samples per country. To ensure the comparability of these values, measurement invariance was assessed using a multigroup confirmatory factor analysis. Covariates characterizing the reference values were selected with the help of regression analyses.ResultsThe confirmatory factor analysis confirmed that the QOLIBRI-OS scores measured the same traumatic brain injury–specific HRQoL construct across the 3 countries. Healthy individuals reported significantly higher HRQoL than individuals with at least 1 chronic health condition. Older age and higher education levels were significantly associated with higher HRQoL.ConclusionsBecause the reference values displayed differences in terms of age and education level across the 3 countries, we recommend using country-specific reference values stratified by sociodemographic and health status in research and clinical practice.

Laparoscopic bilateral inguinal hernia repair: Should it be the preferred technique?

Inguinal hernias are amongst the most common conditions requiring general surgical intervention. For decades, the preferred approach was the open repair. As laparoscopy became more popular and available and more surgeons became familiarized with this modality, laparoscopic inguinal hernia repair became an alternative. The aim of this study is to assess the effectiveness of laparoscopic inguinal repair, with a focus on bilateral inguinal hernias. Initial reports have shown promising clinical outcomes compared to those of conventional repair of bilateral hernias. However, there are only a few studies concerning laparoscopic repair of bilateral hernias. It is yet to be proven that laparoscopy is the “gold standard” in the treatment of bilateral inguinal hernias. So far, the choice of an inguinal hernia repair technique has been up to each surgeon, depending on their expertise and available resources after taking into consideration each patient’s needs.
