Development and evaluation of the Communication over Language Barriers questionnaire (CoLB-q) in paediatric healthcare

Objective

To develop a valid and reliable questionnaire addressing the experiences of healthcare personnel of communicating over language barriers and using interpreters in paediatric healthcare.

Systematic review of organisation‐wide,trauma‐informed care models in out‐of‐home care (OoHC) settings

Trauma in early childhood has been shown to adversely affect children's social, emotional, and physical development. Children living in out‐of‐home care (OoHC) have better outcomes when care providers are present for children, physically, psychologically, and emotionally. Unfortunately, the high turnover of out‐of‐home carers, due to vicarious trauma (frequently resulting in burnout and exhaustion) can result in a child's trauma being re‐enacted during their placement in OoHC. Organisation‐wide therapeutic care models (encompassing the whole organisation, from the CEO to all workers including administration staff) that are trauma‐informed have been developed to respond to the complex issues of abuse and neglect experienced by children who have been placed in OoHC. These models incorporate a range of therapeutic techniques, and provide an overarching approach and common language that is employed across all levels of the organisation. The aim of this study was to investigate the current empirical evidence for organisation‐wide, trauma‐informed therapeutic care models in OoHC. A systematic review searching leading databases was conducted for evidence of organisation‐wide, trauma‐informed, out‐of‐home care studies, between 2002 and 2017. Seven articles were identified covering three organisational models. Three of the articles assessed the Attachment Regulation and Competency framework (ARC), one study assessed the Children and Residential Experiences programme (CARE), and three studies assessed The Sanctuary Model. Risk of bias was high in six of the seven studies. Only limited information was provided on the effectiveness of the models identified through this systematic review, although the evidence did suggest that trauma‐informed care models may have significantly positive outcomes for children in OoHC. Future research should focus on evaluating components of trauma‐informed care models and assessing the efficacy of the various organisational care models currently available.     

Live/Real Time Three‐Dimensional Transesophageal Echocardiographic Assessment of Ventricular Septal Volume and Mass before and after Myectomy in Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is the most common genetically transmitted cardiomyopathy. In patients resistant to medical management, myectomy is the surgical procedure of choice to reduce the symptoms of left ventricular outflow obstruction. Two‐dimensional transesophageal echocardiography (2DTEE) has become part of the operative procedure by decreasing the incidence of postoperative complications. However, because of the three‐dimensional geometry of left ventricular outflow tract, it is unable to comprehensively assess the location and severity of the obstruction and to provide accurate guidance during myectomy. In this study, 10 patients with HCM underwent live/real time three‐dimensional transesophageal echocardiography (3DTEE) intra‐operatively to measure the volume of the resected septum. This volume correlated well with the volume of the resected septal muscle directly obtained using a graduating cylinder containing water (r = 0.9, P < 0.000). 3DTEE may be potentially used as an adjunct to guide the surgeon in performing an adequate myectomy with a lower incidence of residual obstruction and complications such as an iatrogenic ventricular septal defect.     

Orofacial esthetics and dental anxiety: Associations with oral and psychological health

Objective. Severe dental anxiety (DA) is associated with both oral health and psychosocial consequences in what has been described as a vicious circle of DA. The aim of this study was to investigate self-rated orofacial esthetics in patients with DA and its relationship to psychological and oral health. Materials and methods. A consecutive sample of 152 adult patients who were referred or self-referred to a specialized dental anxiety clinic filled out the Orofacial Esthetic Scale (OES) as well as measurements on DA, self-rated oral health and general anxiety and depression. Clinical measures of dental status were also obtained. Results. Compared with the general population, patients with DA had lower ratings of satisfaction on all aspects of their orofacial esthetics, which included the teeth, gingiva, mouth and face, as well as a global orofacial assessment. Furthermore, the perception of the orofacial appearance was related both to dental status and self-rated oral health, as well as to general anxiety and depression. The level of dissatisfaction with the orofacial appearance was similar for both genders, but women reported more regular dental care and better dental status. Conclusions. The results of this study clearly show less satisfaction with dental and facial appearance in patients with DA, and that the self-rating of orofacial esthetics is related to both oral and psychological health. The OES can be used to assess orofacial esthetics in patients with DA.     

Voluntary versus reflex regulation of maximal exercise flow: volume loops

We determined the efficiency with which maximal exercise ventilatory output could be mimicked voluntarily. Five normal subjects exercised to maximal volitional effort and flow:volume and pressure:volume loops, and end-expiratory lung volume (EELV) and breathing pattern were measured. All subjects increased expiratory flow rate and reduced EELV sufficiently so that the forced vital capacity loop was approximated during at least some portion of expiration, but the generation of pleural pressure remained effective, i.e., equal to or only slightly in excess of that required to produce maximal expiratory flow (Pmax). Subsequently, while at rest, subjects used visual feedback and were able to closely mimic the flow:volume, EELV, and breath-timing achieved in maximal exercise; however: (1) expiratory pressures were excessive and usually exceeded average Pmax; (2) abdominal expiratory muscle activity was increased, as indicated by positive shifts in expiratory gastric pressure; and (3) total ventilatory work was increased 15 to 40% greater than that achieved in maximal exercise. Maximal voluntary efforts (MVV) caused EELV to increase and ventilatory work was increased 20 to 300% greater than during maximal exercise. We conclude that accurate determination of maximal effective ventilatory output available for maximal exercise or precise quantitation of the metabolic cost of producing maximal exercise ventilation requires replication of the pressure:volume, breath-timing, and EELV characteristics achieved in maximal exercise.     

The Ser/Thr protein kinase AfsK regulates polar growth and hyphal branching in the filamentous bacteria Streptomyces

In cells that exhibit apical growth, mechanisms that regulate cell polarity are crucial for determination of cellular shape and for the adaptation of growth to intrinsic and extrinsic cues. Broadly conserved pathways control cell polarity in eukaryotes, but less is known about polarly growing prokaryotes. An evolutionarily ancient form of apical growth is found in the filamentous bacteria Streptomyces, and is directed by a polarisome-like complex involving the essential protein DivIVA. We report here that this bacterial polarization machinery is regulated by a eukaryotic-type Ser/Thr protein kinase, AfsK, which localizes to hyphal tips and phosphorylates DivIVA. During normal growth, AfsK regulates hyphal branching by modulating branch-site selection and some aspect of the underlying polarisome-splitting mechanism that controls branching of Streptomyces hyphae. Further, AfsK is activated by signals generated by the arrest of cell wall synthesis and directly communicates this to the polarisome by hyperphosphorylating DivIVA. Induction of high levels of DivIVA phosphorylation by using a constitutively active mutant AfsK causes disassembly of apical polarisomes, followed by establishment of multiple hyphal branches elsewhere in the cell, revealing a profound impact of this kinase on growth polarity. The function of AfsK is reminiscent of the phoshorylation of polarity proteins and polarisome components by Ser/Thr protein kinases in eukaryotes.
