Імунологічні аспекти діагностики та лікування постгістеректомічного синдрому

В статье представлены данные клинико-иммунологического, вегетологического, психологического статуса 80 женщин, страдающих постгистерэктомическими расстройствами с целью поиска оптимальных подходов к терапии. Установлено, что постгистерэктомический синдром сопровождается различными изменениями нейровегетативной регуляции, коррелирующими с гормонально-иммунологическими нарушениями. Стабильные положительные клинико-иммунологические сдвиги у пациенток с постгистерэктомическим синдромом показали высокую эффективность включения иммунокорригирующих препаратов для оптимизации терапевтических мероприятий в борьбе с указанной патологией.Basing on clinical, immunological, vegetologycal investigations in 80 women with posthysterectomy disorders with the purpose of search of optimum pathogenetic approaches to therapy. It has been found that a posthysterectomy syndrome is accompanied by the different changes neyrovegetatic regulationand also psychoemotional disorders. New important hormonal and immunological aspects of pathogenesis were determinated. Stable positive clinical and immunological changes at patients with a postgysterektomy syndrome showed high effect of including of immunological correction for the complex of treatment of patients with this pathology

Potential improvement of pregnancy outcome through prenatal small for gestational age detection

Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA. OBJECTIVE: To assess differences in mode of delivery and pregnancy outcome between prenatally detected and nonprenatally detected small for gestational age (SGA) neonates born at term.STUDY DESIGN: We performed a retrospective multicenter cohort study. All singleton infants, born SGA in cephalic position between 36(0/7) and 41(0/7) weeks gestation, were classified as either prenatally detected SGA or nonprenatally detected SGA. With propensity score matching we created groups with comparable baseline characteristics. We compared these groups for composite adverse perinatal outcome, labor induction, and cesarean section rates.RESULTS: We included 718 SGA infants, of whom 555 (77%) were not prenatally detected. Composite adverse neonatal outcome did not differ statistically significant between the matched prenatally detected and the nonprenatally detected group (5.5 vs. 7.4%, odds ratio [OR] 0.74, 95% confidence interval [CI]: 0.30-1.8). However, perinatal mortality only occurred in the nonprenatally detected group (1.8% [3/163] in the matched cohort, 1.3% [7/555] in the complete cohort). In the propensity matched prenatally detected SGA group both induction of labor (57 vs. 9%, OR 14.0, 95% CI: 7.4-26.2) and cesarean sections (20 vs. 8%, OR 2.9, 95% CI: 1.5-5.8) were more often performed compared with the nonprenatally detected SGA group.CONCLUSION: Prenatal SGA detection at term allows timely induction of labor and cesarean sections thus potentially preventing stillbirth

Natural variability of TRAIL, IP-10, and CRP in healthy adults - The "HERACLES" study

A novel host-protein score (called MMBV) helps to distinguish bacterial from viral infection by combining the blood concentrations of three biomarkers: tumour necrosis factor related apoptosis inducing ligand (TRAIL), interferon gamma induced protein 10 (IP-10), and C-reactive protein (CRP). These host biomarkers are differentially expressed in response to bacterial versus viral acute infection. We conducted a prospective study, with a time series design, in healthy adult volunteers in the Netherlands. The aim was to determine the variability of TRAIL, IP-10, and CRP and the MMBV score in healthy adults across time. Up to six blood samples were taken from each healthy volunteer over a period of up to four weeks. In 77 healthy participants without recent or current symptoms, MMBV scores (maximal) were bacterial in 1.3 % and viral (or other non-infectious etiology) in 93.5 % of participants. There was little variation in the mean concentrations of TRAIL (74.5 pg/ml), IP-10 (113.6 pg/ml), and CRP (1.90 mg/L) as well as the MMBV score. The variability of biomarker measurement was comparable to the precision of the measurement platform for TRAIL, IP-10, and CRP. Our findings establish the mean values of these biomarkers and MMBV in healthy individuals and indicate little variability between and within individuals over time, supporting the potential utility of this novel diagnostic to detect infection-induced changes

Applicability and added value of novel methods to improve drug development in rare diseases

The ASTERIX project developed a number of novel methods suited to study small populations. The objective of this exercise was to evaluate the applicability and added value of novel methods to improve drug development in small populations, using real world drug development programmes as reported in European Public Assessment Reports. The applicability and added value of thirteen novel methods developed within ASTERIX were evaluated using data from 26 European Public Assessment Reports (EPARs) for orphan medicinal products, representative of rare medical conditions as predefined through six clusters. The novel methods included were 'innovative trial designs' (six methods), 'level of evidence' (one method), 'study endpoints and statistical analysis' (four methods), and 'meta-analysis' (two methods) and they were selected from the methods developed within ASTERIX based on their novelty; methods that discussed already available and applied strategies were not included for the purpose of this validation exercise. Pre-requisites for application in a study were systematized for each method, and for each main study in the selected EPARs it was assessed if all pre-requisites were met. This direct applicability using the actual study design was firstly assessed. Secondary, applicability and added value were explored allowing changes to study objectives and design, but without deviating from the context of the drug development plan. We evaluated whether differences in applicability and added value could be observed between the six predefined condition clusters. Direct applicability of novel methods appeared to be limited to specific selected cases. The applicability and added value of novel methods increased substantially when changes to the study setting within the context of drug development were allowed. In this setting, novel methods for extrapolation, sample size re-assessment, multi-armed trials, optimal sequential design for small sample sizes, Bayesian sample size re-estimation, dynamic borrowing through power priors and fall-back tests for co-primary endpoints showed most promise - applicable in more than 40% of evaluated EPARs in all clusters. Most of the novel methods were applicable to conditions in the cluster of chronic and progressive conditions, involving multiple systems/organs. Relatively fewer methods were applicable to acute conditions with single episodes. For the chronic clusters, Goal Attainment Scaling was found to be particularly applicable as opposed to other (non-chronic) clusters. Novel methods as developed in ASTERIX can improve drug development programs. Achieving optimal added value of these novel methods often requires consideration of the entire drug development program, rather than reconsideration of methods for a specific trial. The novel methods tested were mostly applicable in chronic conditions, and acute conditions with recurrent episodes.

How are "teaching the teachers" courses in evidence based medicine evaluated? A systematic review

Background Teaching of evidence-based medicine (EBM) has become widespread in medical education. Teaching the teachers (TTT) courses address the increased teaching demand and the need to improve effectiveness of EBM teaching. We conducted a systematic review of assessment tools for EBM TTT courses. To summarise and appraise existing assessment methods for teaching the teachers courses in EBM by a systematic review. Methods We searched PubMed, BioMed, EmBase, Cochrane and Eric databases without language restrictions and included articles that assessed its participants. Study selection and data extraction were conducted independently by two reviewers. Results Of 1230 potentially relevant studies, five papers met the selection criteria. There were no specific assessment tools for evaluating effectiveness of EBM TTT courses. Some of the material available might be useful in initiating the development of such an assessment tool. Conclusion There is a need for the development of educationally sound assessment tools for teaching the teachers courses in EBM, without which it would be impossible to ascertain if such courses have the desired effect

Evidence-based practice educational intervention studies: A systematic review of what is taught and how it is measured

Abstract Background Despite the established interest in evidence-based practice (EBP) as a core competence for clinicians, evidence for how best to teach and evaluate EBP remains weak. We sought to systematically assess coverage of the five EBP steps, review the outcome domains measured, and assess the properties of the instruments used in studies evaluating EBP educational interventions. Methods We conducted a systematic review of controlled studies (i.e. studies with a separate control group) which had investigated the effect of EBP educational interventions. We used citation analysis technique and tracked the forward and backward citations of the index articles (i.e. the systematic reviews and primary studies included in an overview of the effect of EBP teaching) using Web of Science until May 2017. We extracted information on intervention content (grouped into the five EBP steps), and the outcome domains assessed. We also searched the literature for published reliability and validity data of the EBP instruments used. Results Of 1831 records identified, 302 full-text articles were screened, and 85 included. Of these, 46 (54%) studies were randomised trials, 51 (60%) included postgraduate level participants, and 63 (75%) taught medical professionals. EBP Step 3 (critical appraisal) was the most frequently taught step (63 studies; 74%). Only 10 (12%) of the studies taught content which addressed all five EBP steps. Of the 85 studies, 52 (61%) evaluated EBP skills, 39 (46%) knowledge, 35 (41%) attitudes, 19 (22%) behaviours, 15 (18%) self-efficacy, and 7 (8%) measured reactions to EBP teaching delivery. Of the 24 instruments used in the included studies, 6 were high-quality (achieved ≥3 types of established validity evidence) and these were used in 14 (29%) of the 52 studies that measured EBP skills; 14 (41%) of the 39 studies that measured EBP knowledge; and 8 (26%) of the 35 studies that measured EBP attitude. Conclusions Most EBP educational interventions which have been evaluated in controlled studies focus on teaching only some of the EBP steps (predominantly critically appraisal of evidence) and did not use high-quality instruments to measure outcomes. Educational packages and instruments which address all EBP steps are needed to improve EBP teaching
