Septic Shock with Purpura in Children: an experimental and clinical approach

Septic shock with purpura is a rapidly evolving clinical picture characterized by sepsis (tachycardia, tachypnea, fever), shock (hypotension or signs of end-organ failure) and a spectrum of coagulation disorders (ranging from petechiae, purpura to ecchymoses). It is mainly (80 %) caused by N. meningitidis (group A, B or C). However, occasionally other micro-organisms such as Haemophilus influenzae, Haemophilus aegyptius, Streptococcus group A, group B streptococcus, streptococcus pneumoniae, Staphylococcus aureus, Pseudomonas species and Capnocytophagus canimorsus can be detected as a causative agent. Even viruses can under certain conditions cause a comparable clinical picture. Approximately 80 % of the patients is below the age of 18 years, and 50 % below the age of 5 years. The development of the disease in older patients is partly due to the presence of a deficiency in the immune system (complement deficiency, spleen extirpation, diabetes mellitus). The occurrence in children is related to the absence of antibodies, although it is assumed that these children are healthy except for an agerelated immaturity oftheir immune system. The mortality ranges from 15 - 40 %, depending on the selection of the patients

Bench-to-bedside review: genetic influences on meningococcal disease

This review discusses the possible involvement of a variety of genetic polymorphisms on the course of meningococcal disease. It has been shown that several common genetic polymorphisms can either influence the susceptibility to meningococcal disease or can account for a higher mortality rate in patients. Gene polymorphisms concerning antibody receptors, lipopolysaccharide (LPS) binding receptors or proteins, innate complement proteins as well as cytokines and hemostatic proteins are described. The study of genetic polymorphisms might provide important insights in the pathogenesis of meningococcal disease and could make it possible to identify individuals who are at risk of either contracting or dying from meningococcal disease

The Inflammatory and Hemostatic Response in Sepsis and Meningococcemia

Meningococcemia is notorious for evasion of the host immune system and its rapid progression to fulminant disease, and serves as a unique model for pediatric sepsis. Illness severity is determined by complex interplays among host, pathogen, and environment. The inflammatory host response, including proinflammatory and anti-inflammatory responses in innate and adaptive immunity, skews toward a proinflammatory state. This leads to endothelial dysfunction and activation of the hemostatic response, which may lead to disseminated intravascular coagulation. This article reviews the pathogenesis of sepsis, in particular the inflammatory and hemostatic response in meningococcal sepsis

Construction of a parent satisfaction instrument: Perceptions of pediatric intensive care nurses and physicians

Purpose: The aims of the study were (1) to identify parental satisfaction items through the opinions of pediatric intensive care unit (PICU) nurses and physicians, (2) to reach consensus on the identified items, and (3) to apply factor analysis to evaluate the items and domains toward a PICU parental satisfaction instrument. Materials and Methods: Pediatric intensive care unit nurses and physicians working in 8 university hospitals in the Netherlands participated. A 2-round Delphi method was completed. Confirmatory factor analysis was performed on the satisfaction items and domains. Results: Three hundred two nurses and 62 physicians participated in the Delphi study, and 269 (76%) completed 2 questionnaire rounds. In Delphi round 2, 14 of the 78 items had a mean of less than 8.0 (range, 1 [low importance] to 10 [high importance]). The interquartile range of all domains decreased by almost half, and only 10 satisfaction items had a heterogeneity of less than 70%. Structure determination revealed that 4 satisfaction items needed to be excluded. Out of 74 satisfaction items, 72 showed factor loadings greater than 0.50. The reliability estimates, Cronbach α, for the 6 domains varied from 0.74 to 0.92. Conclusions: Priorities in parental satisfaction measures are identified. The findings are fundamental in the development of a PICU parental satisfaction instrument

Perceptions of parents, nurses, and physicians on neonatal intensive care practices

OBJECTIVE: To identify satisfaction with neonatal intensive care as viewed by parents and healthcare professionals and to explore similarities and differences between parents and healthcare professionals. STUDY DESIGN: A 3-round Delphi method to identify neonatal care issues (round 1) and to determine the importance of these issues (rounds 2 and 3) was conducted among nurses (n = 84) and physicians (n = 14), followed by an exploratory survey among parents (n = 259). Main outcome measures were 92 neonatal care-related items. RESULTS: Sixty-eight nurses and 13 physicians completed all 3 rounds. The first round yielded 419 neonatal care related statements, which were clustered into 92 items. The survey was completed by 148 (57%) parents. Parents rated 25 of 92 care items significantly higher than did the professionals (effect size of Cohen's d, 0.31 to 1.14, P <or= .02). Two items related to medication administration had the largest effect size. Professionals rated 7 items significantly higher than didparents (Cohen's d, -0.31 to -0.58, P <or= .04). One of these was assigning a physician and a nurse to the parents. Three were related to multicultural care. CONCLUSIONS: This study revealed disparities between parents and neonatal intensive care unit staff on a number of care issues reflecting incongruity in rec

Patient values in physiotherapy practice, a qualitative study

Objectives: Physiotherapy is, like all healthcare professions, relational and value-laden. Patient-centred care, evidence-based practice and value-based practices are concepts in which patient values lie at the heart of high-quality healthcare practices. Nevertheless, physiotherapists have limited awareness of what patient values are in the physiotherapy encounter. The purpose of this study is to explore these patient values. Methods: A qualitative study design using content analysis was used involving 17 adult participants with chronic or recurrent musculoskeletal pain. Data were collected during July 2015–July 2016 in three primary care physiotherapy facilities in Rotterdam, The Netherlands. Two researchers analysed the interviews and derived relevant codes from the data. After an iterative process of comparing, analysing, conceptualizing, and discussing the data, a pre-existing analytic framework was refined in which distinct values were delineated. Results: Emerging patient values were encompassed in three themes, each consisting of two to four elements: (1) values about oneself (uniqueness and autonomy), (2) values regarding actions of the professional (technically skilled professional, conscientious professional, compassionate professional, responsive professional) and (3) values regarding interactions between patients and the professionals (partnership and empowerment). Conclusion: This study emphasizes the need for discussing patient values in the clinical encounter and helps physiotherapists to understand what deems to be important for patients with musculoskeletal pain in physiotherapy practice. The results of this study contribute to the existing body of knowledge of this important aspect of the quality of physiotherapy practice and may inspire clinicians and educators to actively implement patient values in clinical practice and the physiotherapy education

Circadian variation of plasminogen-activator-inhibitor-1 levels in children with meningococcal sepsis

Objective To study whether the circadian variation of plasminogen-activator-inhibitor-1 (PAI-1) levels, with high morning levels, is associated with poor outcome of children with meningococcal sepsis presenting in the morning hours. Design Retrospective analysis of prospectively collected clinical and laboratory data. Setting Single center study at Erasmus MC-Sophia Children's Hospital, Rotterdam, the Netherlands. Subjects 184 patients aged 3 weeks to 18 years with meningococcal sepsis. In 36 of these children, PAI-1 levels at admission to the PICU were measured in plasma by ELISA. Interventions None. Measurements and main results Circadian variation was studied by dividing one day in blocks of 6 hours. Patients admitted between 6:00 am and 12:00 am had increased illness severity scores and higher PAI-1 levels (n = 9, median 6912 ng/mL, IQR 5808-15600) compared to patients admitted at night (P = 0.019, n = 9, median 3546 ng/mL, IQR 1668-6118) or in the afternoon (P = 0.007, n = 7, median 4224 ng/mL, IQR 1804-5790). In 184 patients, analysis of circadian variation in relation to outcome showed more deaths, amputations and need for skin grafts in patients admitted to the PICU between 6:00 am and 12:00 am than patients admitted during the rest of the day (P = 0.009). Conclusions Circadian variation of PAI-1 levels is present in children with meningococcal sepsis and is associated with illness severity, with a peak level in the morning. Whether circadian variation is an independent risk factor for morbidity and mortality in meningococcal sepsis needs to be explored in future studies

Relation between cytokines and routine laboratory data in children with septic shock and purpura

Objective To establish the relation between routine laboratory data (lactate, fibrinogen, CRP) and cytokines (TNF,IL-1 and-6) and to estimate their prognostic value in pediatric patients with severe infectious purpura on admission. Design Prospective study. Setting Pediatric intensive care unit (PICU). Patients 17 children aged 5–172 months (median 46) were hospitalized in our PICU in 1989–90 with severe infectious purpura.Neisseria meningitidis was isolated in 15 children andHaemophilus influenzae in two. The patients were divided into 3 groups: non-shock, shock and severe shock leading to death. Shock was defined by standard criteria. Measurements Arterial blood was sampled for lactate, CRP, fibrinogen, TNF, and IL-1 and-6 on admission. The PRISM (pediatric risk of morality)-score was recorded. Methods Statistical analysis was performed with the Student'st-test using the logarithmic values of the cytokine concentration, and Spearman correlation analysis. Results According to the shock criteria, 9 patients were in shock of whom 4 did not survive. Significant differences existed between the 3 groups concerning lactate, TNF, and IL-6. Fibrinogen, CRP, IL-1, and PRISM-score discriminated only between survivors and non-survivors. A highly significant correlation existed between cytokines, the PRISM-score and lactate (TNF:r=0.69, IL-1:r=0.56, IL-6:r=0.65, PRISM:r=0.65). A significant inverse correlation existed between cytokines and CRP (TNF:r=−0.55, IL-1:r=−0.64, and IL-6:r=−0.56), and IL-6 and fibrinogen (r=−0.65). Conclusion These results show a significant correlation between cytokines and lactate, and lactate, TNF and IL-6 are closely associated with the severity of septic shock with purpura in children

An ontological model for the (digital) patient

Ontologies and uniform language are needed to be able to compare large sets of patient data, specifically when applying computer based analyses [1,2]. “Patient” is a frequently used object in healthcare but it lacks a clear definition that can easily be translated into data systems, such as the Electronic Health Record [3], which is needed for interoperability or analysis. The first step in this process is to define an ontological description of the object patient although patient is frequently used in disease ontological descriptions. The work here described is the initial phase in creating a high level ontological description for the patient. It complements the research efforts in clinical decision to

Machine learning with PROs in breast cancer surgery; caution: Collecting PROs at baseline is crucial

As high breast cancer survival rates are achieved nowadays, irrespective of type of surgery performed, prediction of long-term physical, sexual, and psychosocial outcomes is very important in treatment decision-making. Patient-reported outcomes (PROs) can help facilitate this shared decision-making. Given the significance of more personalized medicine and the growing trend on the application of machine learning techniques, we are striving to develop an algorithm using machine learning techniques to predict PROs in breast cancer patients treated with breast surgery. This short communication describes the bottlenecks in our attempt to predict PROs
