Erjia Mao
The field of periodontics has become increasingly discussed and advanced in recent decades. The techniques of periodontal soft tissue grafts are among these advancements. The techniques have been used more and more clinically not only in periodontics, but also in the areas of dental implantology, aesthetics, and orthodontics. In this article, we discuss the clinical indications and the advantages and disadvantages of several autogenous tissue grafts (e.g. pedical grafts, free gingival graft, and subepithelial connective tissue graft)...

Elbow flexion force depends on forearm orientation with supinated and neutral being stronger than pronated. The purpose of this study was to assess the influence of forearm orientation on voluntary activation (VA), postactivation potentiation (PAP), and twitch properties. Eleven males (23 ± 3 years) performed isometric elbow flexion maximal voluntary contractions (MVC) in supinated, neutral, and pronated forearm orientations with supramaximal stimulation to the biceps brachii muscle belly before, during, and after the MVC...

BACKGROUND: Despite evidence supporting the effectiveness of diabetic retinopathy screening (DRS) in reducing the risk of sight loss, attendance for screening is consistently below recommended levels. OBJECTIVES: The primary objective of the review was to assess the effectiveness of quality improvement (QI) interventions that seek to increase attendance for DRS in people with type 1 and type 2 diabetes.Secondary objectives were:To use validated taxonomies of QI intervention strategies and behaviour change techniques (BCTs) to code the description of interventions in the included studies and determine whether interventions that include particular QI strategies or component BCTs are more effective in increasing screening attendance;To explore heterogeneity in effect size within and between studies to identify potential explanatory factors for variability in effect size;To explore differential effects in subgroups to provide information on how equity of screening attendance could be improved;To critically appraise and summarise current evidence on the resource use, costs and cost effectiveness...

The Kidney Allocation System (KAS) was implemented in December 2014 with unknown impact on the pediatric waitlist. To understand the effect of KAS on pediatric registrants, deceased donor kidney transplant (DDKT) rate was assessed using interrupted time series analysis and time-to-event analysis. Two allocation eras were defined with an intermediary washout period: Era 1 (01/01/2013-09/01/2014), Era 2 (09/01/2014-03/01/2015), and Era 3(03/01/2015-03/01/2017). When using Cox proportional hazards, there was no significant association between allocation era and DDKT likelihood as compared to Era 1 (Era 3: aHR: 1...

Currently, there are sophisticated applications that make it possible to visualize medical images and even to manipulate them. These software applications are of great interest, both from a teaching and a radiological perspective. In addition, some of these applications are known as Free Open Source Software because they are free and the source code is freely available, and therefore it can be easily obtained even on personal computers. Two examples of free open source software are Osirix Lite® and 3D Slicer®...

Heart failure with preserved ejection fraction (HFpEF) is characterized by signs and symptoms of HF in the presence of a normal left ventricular (LV) ejection fraction (EF). Despite accounting for up to 50% of all clinical presentations of HF, the mechanisms implicated in HFpEF are poorly understood, thus precluding effective therapy. The pathophysiological heterogeneity in the HFpEF phenotype also contributes to this disease and likely to the absence of evidence-based therapies. Limited access to human samples and imperfect animal models that completely recapitulate the human HFpEF phenotype have impeded our understanding of the mechanistic underpinnings that exist in this disease...

The actual coagulation status may be reliably measured using only highly sensitive global functional tests; however, they are not numerous and all of them have disadvantages. Thrombodynamics (TD), a novel global coagulation test, is sensitive to hypo- and hypercoagulable states. The main properties of this test were investigated, and its capabilities for hemostasis analysis were verified through pharmacodynamic monitoring of the most widely used anticoagulants, heparins. The anticoagulant effects in the plasma of donors (n = 20) and patients after hip replacement (n = 20) spiked with unfractionated heparin or enoxaparin were measured in vitro to eliminate the influence of pharmacokinetic factors...

BACKGROUND: Tuberculosis (TB) remains a major public health problem in resource-poor countries including India. Scientific knowledge is used to guide policy and practice. There is however, a limited, systematically collected data required for guiding the scale-up of interventions particularly amongst vulnerable populations including tribal groups in the country. In view of this, a systematic review of the TB research studies carried out in tribal areas of different parts of the country was undertaken...

Olivia Smith, Jessica Galey
English and Welsh responses to rape have long been critically examined, leading to attempted improvements in the criminal justice system. Despite this, little attention has been paid to the Criminal Injuries Compensation Scheme (CICS) and the difficulties applying it to rape. To begin addressing this gap, researchers interviewed three, and qualitatively surveyed 22, Independent Sexual Violence Advisors. The findings suggest that CICS may not only reinforce rape myths and disadvantage vulnerable survivors, but is also a source of validation and contributes to survivor justice...

Paul S Larson, Philip A Starr, Alastair J Martin
Interventional and intraoperative MRI approaches to deep brain stimulator implantation are relatively new, and in their purest form represent a distinct departure from traditional stereotactic techniques. They employ a novel means of stereotaxis based on regions of interest in the MR space and simple geometric principles, which eliminate the need for a stereotactic frame. This approach is appropriate for targets that are MR visible, and for whom the local anatomy and function are well characterized. It may also be appropriate for targets that do not have a well-described physiologic signature and for which clinical response to macrostimulation does not play a critical role...

The stereotactic frame has served as the gold standard apparatus for accurate and precise targeting of deep brain structures since 1947. Despite passing the test of time, the stereotactic frame has several limitations from the perspective of both neurosurgeons and patients. Therefore, there was a need to develop a frameless system that had equivalent accuracy and reliability to the frame. This need was met with 3 commercially available frameless stereotactic systems designed specifically for deep brain stimulation surgery: Nexframe, STarFix, and ClearPoint...

REVIEW
Magdalena Gumiela
Intensive efforts were undertaken during the last few decades for the separation of cyclotron-produced 99mTc from 99Mo and new papers have been published on this topic since the last review [1]. In the future the cyclotron-based methods can replace reactor-based technology in producing this medical radioisotope and the nuclear reaction 100Mo(p,2n)99mTc appears to be the most worthwhile approach. New ways of producing of 99mTc require efficient separation methods. Several strategies for separation of 99mTc from 99Mo have been already developed...

The simulation training in midwifery has a long tradition. It is aimed at acquiring basic and advanced practical skills such as performing a certain number of births, episiotomy and subsequent suture, assisting during breech birth etc. Midwifery education is currently based on the requirements of the Directives of the European Union exactly specifying number of performed practical procedures and approaches (World Health Organisation (WHO) Europe, 2009). The aim of this paper is to draw attention to the experience with the simulation training from the teacher's point of view in the study program Midwifery in Slovakia...

BACKGROUND: Psychiatric inpatient treatment is increasingly performed in settings with locked doors. However, locked wards have well-known disadvantages and are ethically problematic. In addition, recent data challenges the hypothesis that locked wards provide improved safety over open-door settings regarding suicide, absconding and aggression. Furthermore, there is evidence that the introduction of an open-door policy may lead to short-term reductions in involuntary measures. The aim of this study was to assess if the introduction of an open-door policy is associated with a long-term reduction of the frequency of seclusion and forced medication...

Randomized Controlled Trials (RCTs) are increasingly popular in the social sciences, not only in medicine. We argue that the lay public, and sometimes researchers, put too much trust in RCTs over other methods of investigation. Contrary to frequent claims in the applied literature, randomization does not equalize everything other than the treatment in the treatment and control groups, it does not automatically deliver a precise estimate of the average treatment effect (ATE), and it does not relieve us of the need to think about (observed or unobserved) covariates...

BACKGROUND: Hip dislocations are a common presentation in the Emergency Department (ED) and require urgent reduction to reduce the risk of avascular necrosis. Over 90% of all dislocations can successfully be reduced in the ED and there is evidence that cases awaiting operative reduction result in significant delays. DISCUSSION: While there is limited data comparing specific techniques, the individual success rates of most maneuvers range from 60-90%. Additionally, each technique has distinct advantages and limitations associated with its use...

INTRODUCTION: During the aging process, natural modifications occur in the larynx and the structures involved in phonation which explain the specific characteristics found in the voices of elderly persons. When, at any moment, a voice fails and there is interference with communication, a voice disorder has occurred. This can generate disadvantages in communicative efficiency and have a negative impact on quality of life, compromising mechanisms of socialization, the maintenance of autonomy, and the sense of well-being...

BACKGROUND: Roentgen stereophotogrammetric analysis (RSA) is used to measure early prosthetic migration and to predict future implant failure. RSA has several disadvantages, such as the need for perioperatively inserted tantalum markers. Therefore, this study evaluates low-field MRI as an alternative to RSA. The use of traditional MRI with prostheses induces disturbing metal artifacts which are reduced by low-field MRI. The purpose of this study is to assess the feasibility to use low-field (0...
