ReviewThe effectiveness of selective thoracic fusion for treating adolescent idiopathic scoliosis: a systematic review protocol.
The objective of this review is to assess the effectiveness of selective thoracic fusion as a form of treatment in adolescent idiopathic scoliosis (AIS). This will be compared with all other forms of operative management for major structural thoracic curves. ⋯ Scoliosis is defined as a lateral curvature of the spine of at least 10 degrees, as measured by the Cobb angle. It can be categorized into three broad categories - neuromuscular, congenital and idiopathic. Of these categories, idiopathic is by far the most common, and is a diagnosis of exclusion. Idiopathic scoliosis can then be further broken down into categories based on age of onset. Of these, AIS (children presenting at 10 years of age or older) accounts for 80-85% of cases.Scoliosis curves have a proven complex deformity, consisting of a three-dimensional deformity involving the coronal, sagittal and rotational planes. Each curve (of which there may be many in one patient) can be described with an apex (the vertebra with the greatest lateral distance from the centre of the spine) and the two vertebrae at the end of the curve (named the end vertebrae). The Cobb angle, measured by the intersection of parallel lines from the endplates of the superior and inferior end vertebrae, is the standard way of quantifying the magnitude of scoliosis curves.Major or primary curves are the largest abnormal curves as classified by the Cobb angle. These curves are almost always structural. In addition, secondary or tertiary curves are described as structural if the Cobb angle cannot be reduced to under 25 degrees, on side bending radiographs. Due to the permanent nature of physiological and morphological change of the vertebral bodies and ligaments, structural curves will usually progress as the patient matures, usually at 1 degree per year after maturity. Non-structural curves usually do not progress as the patient matures; instead they are hypothesized to be a product of the body's instinctive nature to provide truncal balance.For many years spinal surgeons have been debating whether a more rigid and straighter spine or a mobile and less straight spine provides better outcomes. The treatment for AIS can include both an operative and non-operative approach. However when the Cobb angle is above 40, the likelihood of curve progression is high and surgical treatment is warranted.Although technology has advanced, the primary goals for operative management have remained constant. The primary goals of surgical treatment in AIS should be to optimize coronal and sagittal correction and avoid further curve progression. This involves not only correction of the major primary curve but also any minor (secondary) curves, while maintaining adequate thoracic kyphosis and lumbar lordosis. Ideally, a balance should be struck between fusing the lowest number of mobile segments and properly correcting the existing deformity. This is where selective spinal fusion has a role to play.The premise of selective thoracic fusion is that after fixation of the primary thoracic curve, there is spontaneous coronal correction of the unfused lumbar curve. Thus the thoracic curve can be exclusively fused to allow for a more mobile lumbar spine. This has been described in studies since the 1950s. However since then, results have varied greatly in the extent of spontaneous lumbar correction. Studies have shown that the degree of spontaneous correction of the lumbar spine is somewhat close to the correction of the thoracic curve; however the extent of optimal correction that can be achieved is uncertain.The alternative to selective thoracic infusion involves complete fusion of both the primary thoracic and secondary lumbar curve in a consecutive series. This can be done via either an anterior or a posterior approach. Complete fusion gives better correction of both curves. It also diminishes the risk of coronal decompensation, adding on phenomenon, junctional kyphosis and eventual revision surgery. However this needs to be calculated against the risk of sagittal decompensation, increased risk of lumbar degeneration and chronic back pain, all of which seem to be more prevalent in patients with fusion of both curves.Another goal of surgical intervention is the need to avoid complications. Examples of complications of selective spinal fusion include: junctional kyphosis, coronal imbalance, adding-on and revision surgery. Junctional kyphosis is described as kyphosis of over 10 degrees more than pre-operative measurements. This is measured by the angle between the inferior end plate of the highest instrumented vertebrae and the superior end plate of the vertebra two levels higher. Coronal imbalance is when the distance between the C7 plumb line and the central sacral vertical line is greater than 2 centimeters. The adding-on phenomenon is described as progression or extension of the primary curve after fusion.In 2001, Lenke et al reported a classification for AIS that has been able to identify those patients who may benefit from a selective spinal fusion (1C, 2C, 5C). A three-tiered approach is used with the Lenke classification system involving curve type, lumbar modifier and sagittal modifier. Firstly the curves of the spinal column (proximal thoracic, main thoracic and thoracolumbar/lumbar) are classified as structural or non-structural before a lumbar modifier (A, B, C) based on the distance from the central sacral vertical line and the lumbar apical vertebra is applied. Further classification is then undertaken measuring the kyphosis of the thoracic curve T5-T12 (-, N, +).Lenke proposed that a selective thoracic fusion could be undertaken when the primary curve is structural and the compensatory lumbar curve is non-structural and that additionally certain radiological criteria were met such as the Cobb angle magnitude, apical vertebral translation and rotation. These are all objective markers that can be accurately measured on plain radiographs, with good inter-and intra-observer reliability.However all surgeons do not routinely accept these treatment guidelines. It has been reported that only approximately 49-67% of experienced surgeons are performing a selective thoracic fusion in Lenke 1C curves. This may be due to the fear of complications (of which the rates are relatively unknown) and well as misunderstanding of how much correction can be achieved by the un-fused compensatory lumbar curve. A search of PubMed, the Cochrane Library, PROSPERO and the JBI Databases of Systematic Reviews and Implementation Reports found no current systematic review assessing the effectiveness of selective thoracic fusion compared to other approaches. As such, the aim of this review is to evaluate and critically appraise available evidence on selective thoracic fusion in order to provide a suitable estimate of the radiological and functional outcomes of this type of surgical intervention as well as the approximate complication rate in order to give patients correct information prior to their providing their informed consent.

ReviewThe effectiveness of health literacy interventions on the informed consent process of health care users: a systematic review protocol.
The aim of this systematic review is to establish the best available evidence of the effectiveness of health literacy interventions on the informed consent process for health care users. The specific review question is:What is the effectiveness of health literacy interventions on health care users' informed consent to health procedures processes? ⋯ Informed consent is a fundamental principal in the health care context which nowadays includes the patient's capacity to judge and to be involved in the decision making concerning their care that ensures that the care received reflects their goals, preferences and values. The importance of obtaining a valid consent before any medical procedure is well-established. In a US court case in 1914, it was stated that it is the right of any adult with the capability of making decisions concerning his own body, and that any surgical operation without the patient's consent could be considered as an assault. In another US court case, the court stated that it is a doctor's duty to make a reasonable disclosure to his patient of the nature, probable consequences and dangers of the proposed treatment to the patient. The application of the doctrine of informed consent as a legal procedure may slightly differ from country to country or from state to state, and may have different forms even within the same country. For example in the UK, consent can be written, verbal or non-verbal/implied, and a written consent form is not the actual consent itself but merely serves as evidence that consent has been given. If the elements of voluntariness, appropriate information and capacity have not been satisfied, a signed informed consent form will not make the consent valid. Nowadays it is widely accepted that prior to the application of any medical procedure, its benefits, risks and alternatives must have been explained to the patient, and the competent patient should have voluntarily and understandingly consented. Hence, the informed consent refers both to the health professional's obligation of information disclosure to the patient and to the quality of the patient's understanding and decision making. In other words, it does not refer to the single moment of the agreement, but to the whole complex process of gaining information, deciding and consenting. Several factors may restrict informed consent, including the patient's competence, provision of limited information, ineffective communication between patients and professionals, the hospital environment itself and privacy problems.According to the World Health Organization (WHO), people are increasingly urged to make choices for themselves or for their family members in regards to health care use. However, at the same time, inadequate or problematic health literacy skills have been reported in approximately half of the adult population in eight European countries. "Health literacy is linked to literacy and entails people's knowledge, motivation and competences to access, understand, appraise and apply health information in order to make judgments and take decisions in everyday life concerning health care, disease prevention and health promotion to maintain or improve quality of life during the life course". There are many instruments measuring either health literacy in general or some dimensions of health literacy (e.g. numeracy), health literacy related to specific issues (e.g. nutrition, diabetes) or health literacy of specific populations (e.g. adolescents). The diversity of existing instruments, which includes diversity in terms of scoring and ranges, makes the comparison of the results of different studies difficult. Index thresholds and ranges for different levels of health literacy for most tools were set based either on that of other well established health literacy instruments used in the same study, or on experts' assessments of the required health literacy scores. Adequate health literacy could be considered as the capacity of successfully completing most tasks required to function in the health care setting.Low or inadequate health literacy has been found to have several adverse effects on health and health care use: reduced ability to take medications properly and to interpret labels and health messages, poorer overall health status and higher risk of mortality in seniors, increased emergency department and hospital use, and decreased use of preventive interventions.Most studies examining the relationship between health literacy and informed consent conclude that patients with low health literacy are less likely to participate in decision making concerning their health care. According to a recent literature review, health care users' literacy, together with other factors, were found to be important determinants of a patient's capacity to provide fully informed consent. According to this review, 21 to 86% of the patients were able to recall the potential risks and complications of their medical procedure. This percentage may be even lower because most of the included studies referred to self-reported recall, which may be a flawed measure. According to the literature, much of the written material related to the informed consent is too difficult for health care users to understand. In addition, in their study, McCarthy et al. observed that during consultations, physicians spoke and used significantly more complex language than their patients, which may result in inappropriate communication for the patients, mainly for those with limited literacy. The situations described above may raise a number of critical legal and ethical problems. Health professionals, who shape the conditions of interactions with the patient, are responsible for adapting appropriate interventions, such as communication approaches that take into account patients' health literacy. These interventions could have a major contribution to the improvement of the informed consent process.Sheridan et al. conducted a systematic review on interventions designed to reduce the effects of limited health literacy in general. Some of the outcomes of the included studies were comprehension and behavioral intent, outcomes which could be strongly related to the informed consent process. Without making any distinction of the studies referring to the informed consent process, they conclude that several health literacy interventions, for example, adding video to narrative, could improve an individual's comprehension. Schenker et al. conducted a systematic review on the interventions to improve patient comprehension of medical and surgical procedures, including articles published until 2008. One of their conclusions was that, in most studies, while particular attention is needed for interventions provided to patients with limited literacy, the literacy of the patients was not addressed or assessed.Since then, many articles on health literacy and informed consent have been published. According to a recent review on best practices and new models of health literacy for informed consent, which includes papers published from 2004 to 2014, over half of the collected articles were published since 2010. This review, which is limited to literature within the US and its territories, and does not focus on the evaluation of the recommended practices in the literature, concludes that different tactics for simplifying written documents and clarifying verbal exchanges, and the use of multimedia formats and computerized exchanges might ameliorate constraints to health literate communications required for informed consent.Studies have evaluated the effectiveness of health literacy interventions which aim to improve the informed consent process. Improvement of the informed consent process may refer not only to the patients' comprehension but also, for example, to the recall of the information provided, to their intention to ask for clarifications, or to their satisfaction with the procedure. Interventions described and tested in the literature focus on the improvement of the print material, the process (e.g. the communication of the appropriate information) or both. Davis et al. conducted a randomized controlled trial to compare two polio vaccine pamphlets written at a sixth grade level - an international standardized pamphlet and an easy-to-read pamphlet - for the comprehension and preference among parents. Although the parents in the intervention group (N=304) achieved significantly higher comprehension than the control group (N=306) (65% vs 60%, p<0.005), the authors concluded that simplifying written material increases appeal but not the comprehension to an adequate level without use of instructional graphics. Similarly, Lorenzen et al. found that a reader friendly informed consent document to surgical procedures was more commonly read by the health care users as compared to the original consent document; however, no difference was found in terms of the participants' capacity to describe the procedure in their own words. Kang et al. evaluated recall and comprehension of orthodontic informed consent among pairs of children and their parents (N=90) applying three different informed consent procedures. According to this study, a combination of improving the readability of consent materials and the informed consent process (audio and visual cues) led to better recall for the patients and better recall and comprehension for their parents compared to an improved readability form or the usual informed consent form. Smith et al. used a randomized controlled trial to compare a decision aid (booklet and DVD) specifically designed for adults with low literacy skills (N=357) with a standard information booklet (N=173) on screening for bowel cancer. They found that the proportion of participants making an informed choice was 22% higher in the intervention group than in the control group (34% vs 12%, P<0.001). Matsuyama et al.

ReviewDo First Generation Immigrant Adolescents Face Higher Rates of Bullying, Violence and Suicidal Behaviours Than Do Third Generation and Native Born?
We conducted a systematic review to examine first generation immigrant adolescents' likelihood of experiencing bullying, violence, and suicidal behaviours compared to their later-generation and native born counterparts, and to identify factors that may underlie these risks. Eighteen studies met full inclusion criteria. First generation immigrant adolescents experience higher rate of bullying and peer aggression compared to third generation and native counterparts. ⋯ Family cohesion was associated with lower rates of violence. Suicidal ideation was lower across most immigrant adolescents' ethnicities, with the exception of Turkish and South Asian Surinamese female adolescents in the Netherlands. Bullying and peer aggression of immigrant children and adolescents and potential mitigating factors such as family cohesion warrant research and program attention by policymakers, teachers and parents.

ReviewFamilial hypercholesterolaemia in children and adolescents: gaining decades of life by optimizing detection and treatment.
Familial hypercholesterolaemia (FH) is a common genetic cause of premature coronary heart disease (CHD). Globally, one baby is born with FH every minute. If diagnosed and treated early in childhood, individuals with FH can have normal life expectancy. ⋯ Identifying FH early and optimally lowering LDL-C over the lifespan reduces cumulative LDL-C burden and offers health and socioeconomic benefits. To drive policy change for timely detection and management, we call for further studies in the young. Increased awareness, early identification, and optimal treatment from childhood are critical to adding decades of healthy life for children and adolescents with FH.
