Neurodevelopmental outcomes of extremely preterm infants: theoretical and epidemiological perspectives to guide shared-care decision-making

Although births below 28 completed weeks' of gestation contribute to less than 1% of all preterm births globally, the impact of extreme prematurity (EPT) on neurodevelopmental outcomes across the life-course is disproportionately large. Higher rates and increased severity of neurodevelopmental impairments (NDIs) are reported among extremely preterm infants (EPIs). Cognitive skills, motor skills (manifesting as cerebral palsy) and vision are most commonly affected, with effects pervasive throughout school, adolescence and early adulthood. In addition, poorer academic outcomes and higher rates of psychiatric morbidity are seen among EPTs. Consistent improvements in EPI survival in recent years has not been matched with improvements in neurodevelopmental outcomes, especially for those born at less than 25 gestational weeks. However, over the last 20 years, several national and cross-national cohort studies have helped advance our understanding of extreme prematurity's developmental and life-course consequences. Here we provide an overview of the key findings from 13 multi-centre cohorts measuring neurodevelopmental outcomes and discuss the theoretical and epidemiological perspectives of NDIs in the context of extreme prematurity to guide communication with families and shared care decision-making.     

A European evaluation of the patients’ role in clinical education: A six-country cross sectional study

AimThe aim of this study was to analyse the patients’ role in clinical education in terms of facilitative student-patient relationship in Finland, Germany, Iceland, Ireland, Lithuania and Spain and factors promoting a more facilitative relationship in clinical education.BackgroundNursing students’ bedside learning is reliant on patients and the establishment of a person-centred approach develops from the relationships with patients.DesignA multi-country, cross-sectional design was implemented.MethodsSurvey data were collected from graduating nursing students and patients between May 2018 and March 2019. The survey consisted of a 13-item facilitative sub-scale of the Student-Patient Relationship Scale as the main outcome measure, which was identical for both populations. In addition, background factors were surveyed with single questions and other scales. Associations between facilitative relationship and background factors were studied with linear models.ResultsAltogether, 1796 students and 1327 patients answered the survey. Overall, both students and patients regarded their relationship as facilitative, but students’ (median 4.23, 95% confidence interval 4.15–4.23) evaluations were higher than patients’ (median 3.75, 95% confidence interval 3.69–3.77). The students’ and patients’ evaluations differed from each other significantly in all other countries except in Ireland and Lithuania. Corresponding associations for both populations were found in terms of the country and students’ cultural confidence.ConclusionsResults signal favourable grounds for students’ bedside learning and patient participation in clinical education with the potential to foster a person-centred approach.     

The EQ-HWB: Overview of the Development of a Measure of Health and Wellbeing and Key Results

ObjectivesExisting measures for estimating quality-adjusted life-years are mostly limited to health-related quality of life. This article presents an overview of the development the EQ-HWB (EQ Health and Wellbeing), which is a measure that encompasses health and wellbeing.MethodsStages: (1) Establishing domains through reviews of the qualitative literature informed by a conceptual framework. (2) Generation and selection of items to cover the domains. (3) Face validation of these items through qualitative interviews with 168 patients, social care users, general population, and carers across 6 countries (Argentina, Australia, China, Germany, United Kingdom, United States). (4) Extensive psychometric testing of candidate items (using classical, factor analysis, and item response theory methods) on > 4000 respondents in the 6 countries. Stakeholders were consulted throughout.ResultsA total of 32 subdomains grouped into 7 high-level domains were identified from the qualitative literature and 97 items generated to cover them. Face validation eliminated 36 items, modified 14, and added 3. Psychometric testing of 64 items found little difference in missing data or problems with response distribution, the conceptual model was confirmed except in China, and most items performed well in the item response theory in all countries. Evidence was presented to stakeholders in 2 rounds of consultation to inform the final selection of items for the EQ-HWB (25-item) and the short version of EQ-HWB (9-items).ConclusionsEQ-HWB measures have been developed internationally for evaluating interventions in health, public health, and social care including the impact on patients, social care users, and carers.     

Fourteen years of the Pregnancy Registry on maternal immunisation with a reduced-antigen-content tetanus-diphtheria-acellular pertussis (Tdap) vaccine

BackgroundGSK initiated a Pregnancy Registry in the United States (US) for the reduced-antigen-content tetanus-diphtheria-acellular pertussis (Tdap; Boostrix, GSK) vaccine with the aim to detect and describe pregnancy outcomes in women vaccinated with Boostrix 28 days before estimated conception or during pregnancy.MethodsVoluntary reports of pregnancy exposure to Boostrix received from spontaneous and post-marketing surveillance sources in the US were assessed. Reports were classified as prospective or retrospective based on the knowledge of pregnancy outcomes at the time of reporting. For completeness, reports of exposure to Boostrix or to the Tdap-inactivated poliovirus vaccine (Boostrix-IPV, GSK) reported to the global safety database from countries outside the US were also evaluated.ResultsFrom May 2005 to August 2019, 1517 (1455 prospective and 62 retrospective) pregnancy reports were received in the Boostrix US Pregnancy Registry. Of the prospective reports, 250 had known outcomes: 244 live infants with no apparent birth defects (BDs), three live infants with BDs, and three spontaneous abortions with no apparent BDs. Of the retrospective reports, 55 had known outcomes: 33 live infants with no apparent BDs, 16 live infants with BDs, one spontaneous abortion with no apparent BDs, four stillbirths with no apparent BDs, and one stillbirth with BDs. Cumulatively, 1321 pregnancy reports (1006 for Boostrix; 315 for Boostrix-IPV) were received from countries outside the US. Of these, 163 prospective reports and 551 retrospective reports had known outcomes. Results were in line with those from the Boostrix US Pregnancy Registry.ConclusionsData currently available from the Boostrix US Pregnancy Registry and from countries outside the US suggested that exposure to Boostrix or Boostrix-IPV during pregnancy does not raise safety concerns related to adverse pregnancy outcomes or BDs.     

结核性脑膜炎临床诊断评分体系的建立及评价研究

背景 结核性脑膜炎（TM）是临床常见的中枢性感染的一种，其起病较慢，症状不典型，病原学诊断困难，误诊率高。目前有效的TM诊断工具较少。利用常见的临床症状、检查指标等建立诊断评分系体可提高诊断准确率，减少误诊。 目的 建立TM临床诊断评分体系（TMCDS），并对其应用价值进行初步评价。 方法 选取2011年11月至2021年9月在柳州市人民医院感染病科住院并诊断为脑膜炎的患者187例为研究对象，采用SPSS 21.0统计软件将患者随机分成建模组（147例）和验模组（40例）。根据是否为TM将建模组分为非TM亚组（76例）和TM亚组（71例）。收集患者的一般资料，主要包括性别、年龄、临床症状（发热、头痛、意识障碍、颈抵抗），实验室及影像学检查结果，包括人类免疫缺陷病毒（HIV）感染情况、CD4+ T淋巴细胞计数、C反应蛋白、颅内压、脑脊液常规生化检查（糖、氯、蛋白、细胞数）。建模组采用多因素Logistic回归分析探讨TM的影响因素；根据每个因素的β值所占比重设立相应分值，建立TMCDS；采用受试者工作特征曲线（ROC曲线）分析TMCDS诊断TM的价值。 结果 两亚组头痛、HIV感染、CD4+ T淋巴细胞计数<200/μl、C反应蛋白升高、颅内压>200 mm H2O（1 mm H2O=0.009 8 kPa）、脑脊液糖降低、脑脊液氯降低、脑脊液蛋白升高、脑脊液单核细胞升高情况比较，差异有统计学意义（P<0.05）。多因素Logistic回归分析结果显示，头痛、CD4+ T淋巴细胞<200/μl、C反应蛋白升高、脑脊液糖降低、脑脊液蛋白升高均是TM的影响因素（P<0.05）。将以上5个影响因素同时结合临床经验纳入脑脊液氯、脑脊液细胞数再次进行多因素Logistic回归分析，结果显示，头痛、CD4+ T淋巴细胞<200/μl、C反应蛋白升高、脑脊液糖降低、脑脊液蛋白升高均是TM的影响因素（P<0.05）。根据上述7个因素β值建立评分系统，将脑脊液氯降低β值设定为1分，其他因素β值与其的倍数即为该因素所对应的分值，因2个影响因素评分为负值，为方便临床，每个因素对应分值增加2.5分，最终建立TMCDS。TMCDS诊断建模组TM的ROC曲线下面积（AUC）为0.807〔95%CI（0.735，0.879），标准误=0.037，P<0.001〕，最佳诊断界值为21.50分。TMCDS诊断验模组TM的AUC为0.766〔95%CI（0.610，0.921），标准误=0.079，P=0.004〕，灵敏度为0.789，特异度为0.667。 结论 通过7个变量建立的TMCDS简单易行，对于早期TM具有较高的临床诊断价值。

Characterizing Standardized Functional Data at Inpatient Rehabilitation Facilities

ObjectiveThe Improving Medicare Post-Acute Care Transformation Act of 2014 mandates using standardized patient functional data across post-acute settings. This study characterized similarities and differences in clinician-observed scores of self-care and transfer items for the standardized section GG functional domain and the functional independent measure (FIM) at inpatient rehabilitation facilities.DesignWe conducted secondary analyses of 2017 Uniform Data System for Medical Rehabilitation national data. Patients were assessed by clinicians on both section GG and FIM at admission and discharge. We identified 7 self-care items and 6 transfer items in section GG conceptually equivalent with FIM. Clinician-assessed scores for each pair of items were examined using score distributions, Bland-Altman plot, correlation (Pearson coefficients), and agreement (kappa and weighted kappa) analyses.Setting and ParticipantsIn all, 408,491 patients were admitted to Uniform Data System for Medical Rehabilitation-affiliated inpatient rehabilitation facilities with one of the following impairments: stroke, brain dysfunction, neurologic condition, orthopedic disorders, and debility.MeasuresSection GG and FIM.ResultsPatients were scored as more functionally independent in section GG compared with FIM, but change score distributions and score orders within impairment groups were similar. Total scores in section GG had strong positive correlations (self-care: r = 0.87 and 0.95; transfer: r = 0.82 and 0.90 at admission and discharge, respectively) with total FIM scores. Weak to moderate ranking agreements with total FIM scores were observed (self-care: kappa = 0.49 and 0.60; transfers: kappa = 0.43 and 0.52 at admission and discharge, respectively). Lower agreements were observed for less able patients at admission and for higher ability patients of their change scores.Conclusions and ImplicationsOverall, response patterns were similar in section GG and FIM across impairments. However, variations exist in score distributions and ranking agreement. Future research should examine the use of GG codes to maintain effective care, outcomes, and unbiased reimbursement across post-acute settings.
