The impact of transfusion of leucodepleted platelet concentrates on cytomegalovirus disease after allogeneic stem cell transplantation

The impact of transfusion of leucodepleted platelet concentrates (PCs) on cytomegalovirus (CMV) disease was assessed in 215 allogeneic (145 unrelated and 70 related donor) transplants over 3 years. In 43%, both donor and patient were CMV seronegative (CMV-/-). All received CMV-seronegative red cells and random leucodepleted PCs. No CMV disease occurred in any CMV-/- (low risk) transplant. CMV infection occurred in 31 seropositive patients (26%); 13 died and five deaths were attributable to CMV disease. When compared with historical controls, who received CMV-seronegative PCs, we found no difference in transfusion-acquired CMV in the current cohort.

N-Terminal Pro–B-Type Natriuretic Peptide in the Emergency Department: The ICON-RELOADED Study

Background

Contemporary reconsideration of diagnostic N-terminal pro–B-type natriuretic peptide (NT-proBNP) cutoffs for diagnosis of heart failure (HF) is needed.

Mental Well‐Being Mediates the Relationship between Perceived Stress and Perceived Health

The association between stress and health has been well researched in the past; however, comparatively few mediators have been tested to understand the underlying mechanism. With increasing awareness on mental well‐being, this study evaluated the relationship between perceived stress and perceived health and examined mental well‐being as a mediator. Two‐hundred undergraduates aged 21 to 26 years completed the English Perceived Stress Scale, Health Status Questionnaire and Asian Mental Well‐Being Scale that assess perceived stress, perceived health and mental well‐being, respectively. Factor analysis and structural equation modelling on the Perceived Stress Scale replicated the reported two‐factor structure after excluding an insignificant item. Linear multiple regression analyses indicated that perceived stress was negatively associated with perceived health. Results showed that mental well‐being partially mediated the relationship between perceived stress and perceived health, although it is acknowledged that this association could be bidirectional. Findings from the present study suggest that future research could focus on reducing stress and improving mental well‐being to alleviate the effect of stress on health.

Evaluation of the impact of a clinical pathway on the organization of a multidisciplinary dental sleep clinic

Purpose

Clinical pathways are used to organize complex care processes by providing structure and standardization. The multidisciplinary approach of oral appliance (OA) therapy for sleep-disordered breathing (SDB) is a complex and dynamic process suitable for such a structured pathway approach.

Methods

A clinical pathway for patients referred for OA therapy was developed and implemented. The aim of this study was to evaluate the impact of this clinical pathway on the time to delivery of the OA and the organization of the multidisciplinary dental sleep clinic (MDSC). The latter was achieved using the care process self-evaluation tool (CPSET).

Results

First, development and implementation of the clinical pathway gave structure and shortened the mean time to delivery by 102 days (240?±?70 vs. 138?±?33 days) (Mann–Whitney U: P?<?0.001). Second, the CPSET scores were obtained in a cohort of 49 healthcare professionals involved in the pathway. Overall, patient-focused organization received the highest scores (80.5?±?9.0 %), whereas cooperation with primary care received the lowest score (66.7?±?12.4 %).

Conclusions

This is the first project on clinical pathways in OA therapy for SDB. The implementation of the pathway in our MDSC has created a significant shortening of the time to delivery. A first evaluation of the clinical pathway using the CPSET scores indicates that all disciplines involved should be thoroughly informed in an ongoing approach.     

Neurologic Manifestations of Angelman Syndrome

Angelman syndrome is a neurogenetic disorder characterized by the loss or reduction of the ubiquitin-protein ligase E3A enzyme. Angelman syndrome results from a deletion or mutation of the maternally inherited 15q11.2-13.1 region, paternal uniparental disomy of chromosome 15, or an imprinting error. Epilepsy is common and may present with multiple seizure types, including nonconvulsive status epilepticus. Seizures are often intractable and typically require broad-spectrum antiepileptic medications. Dietary therapy has also proved successful in Angelman syndrome. Electroencephalographic patterns include notched δ and rhythmic θ activity and epileptiform discharges. Sleep disorders are also common, often characterized by abnormal sleep-wake cycles. Movement disorders are nearly universal in Angelman syndrome, most frequently presenting with ataxia and tremor. Neurocognitive impairment is always present to varying degrees, and expressive speech is typically severely affected. Individuals with Angelman syndrome often manifest psychiatric comorbidities including hyperactivity, anxiety, and challenging behaviors such as aggression and self-injury. We focus on a comprehensive whole-child approach to the diagnosis and long-term clinical care of individuals with Angelman syndrome.
