The current investigation conducted descriptive analyses on key variables in community-based residential (CBR) settings and investigated the extent to which disruptive youth between the ages of 13 and 17 years improved based on therapists' reported alignment with using practices derived from the evidence-base (PDEBs). Results from both the descriptive analyses and multilevel modeling suggested that therapists are using practices that both do and do not align with the evidence-base for disruptive youth. In addition, both PDEBs and practices with minimal evidence-support predicted or marginally predicted final average progress rating for these youth.

Introduction: Peri-implantitis is an inflammation of the soft and hard tissues surrounding an implant that results in the destruction of alveolar bone. Surgical flaps are usually elevated to allow for thorough debridement and disinfection of the implant surface. This frequently results in gingival recession, crown margin exposure, and a poor esthetic result.

The CRISPR-Cas9 system has revolutionized gene editing both at single genes and in multiplexed loss-of-function screens, thus enabling precise genome-scale identification of genes essential for proliferation and survival of cancer cells. However, previous studies have reported that a gene-independent antiproliferative effect of Cas9-mediated DNA cleavage confounds such measurement of genetic dependency, thereby leading to false-positive results in copy number-amplified regions. We developed CERES, a computational method to estimate gene-dependency levels from CRISPR-Cas9 essentiality screens while accounting for the copy number-specific effect.

Aims: Heart failure (HF) is a multi-organ, pro-inflammatory syndrome that impairs bone metabolism. Pro-inflammatory cytokines and bone catabolism enhance periodontal disease, a local inflammatory, bacteria-induced disease that causes bone loss and periodontal soft tissue destruction.

Methods And Results: Medical and dental examinations were performed on patients with HF ( = 39), following heart transplantation (post-HTx,  = 38) and controls ( = 32).

Although significant progress has been made in the identification of youth evidence-based practices, the adoption of these interventions into community-based mental health care remains limited. Dissemination and implementation (DI) research has the potential to bridge this science-practice gap in clinical psychology. The theory of planned behavior (TPB) offers a useful conceptualization of individual behavior change including behavioral intention as defined by attitudes, subjective norms, and perceived behavioral control.

Background: Lack of timely medication intensification and inadequate medication safety monitoring are two prevalent and potentially modifiable barriers to effective and safe chronic care. Innovative applications of health information technology tools may help support chronic disease management.

Objective: To examine the clinical impact of a novel health IT tool designed to facilitate between-visit ordering and tracking of future laboratory testing.

Background: Recent studies in Guyana and Suriname unveiled diminished efficacy of artemisinin derivatives based on day-3 parasitaemia. The migrant characteristics of the population at risk and the potential development of resistance pose a serious health threat in the region. Assessment of factors that may have contributed to this situation is warranted, and analysis of the data generated in those countries on quality and pharmaceutical managements of anti-malarials may contribute to a better understanding of this occurrence.

The purpose of this small pilot study was three-fold: (a) to begin development of a coding scheme for supervisor and therapist skill acquisition, (b) to preliminarily investigate a pilot train-the-trainer paradigm for skill development, and (c) to evaluate self-reported versus observed indicators of skill mastery in that pilot program. Participants included four supervisor-therapist dyads (N = 8) working with public mental health sector youth. Master trainers taught cognitive-behavioral therapy techniques to supervisors, who in turn trained therapists on these techniques.

Hawaii's Child and Adolescent Mental Health Division provides a unique illustration of a youth public mental health system with a long and successful history of large-scale quality improvement initiatives. Many advances are linked to flexibly organizing and applying knowledge gained from the scientific literature and move beyond installing a limited number of brand-named treatment approaches that might be directly relevant only to a small handful of system youth. This article takes a knowledge-to-action perspective and outlines five knowledge management strategies currently under way in Hawaii.

This article reviews the evidence for the evaluation and management for patients with dysphonia. The evidence behind laryngoscopy, laryngostroboscopy, laryngeal imaging, laryngeal electromyography, and disease-specific questionnaires are reviewed. The evidence for management of some of the common conditions leading to dysphonia is also reviewed.

Background: The objective of this study was to implement a rapid assessment of the performance of four malaria control strategies (indoor spraying, insecticide-treated bed nets, timely diagnosis, and artemisinin-based combination therapy) using adequacy criteria. The assessment was carried out in five countries of the Amazon subregion (Bolivia, Colombia, Ecuador, Guyana, and Peru).

Methods: A list of criteria in three areas was created for each of the four strategies: preliminary research that supports the design and adaptation of the control strategies, coverage of the control strategies and quality of the implementation of the strategies.

Background: National malaria control programmes must deal with the complex process of changing national malaria treatment guidelines, often without guidance on the process of change. Selecting a replacement drug is only one issue in this process. There is a paucity of literature describing successful malaria treatment policy changes to help guide control programs through this process.

Objectives: This study investigates the efficacy of recombinant fusogenic VSV [rVSV-NDV/F(L289A) or rVSV-F] in the treatment of head and neck squamous cell carcinoma (HNSCC).

Study Design And Setting: The in vitro replication and cytotoxicity of rVSV-F were studied in two human SCC cell lines, in one murine SCC cell line, and in human keratinocytes. The effects on tumor size and animal survival were investigated following in vivo rVSV-F treatment of floor-of-mouth tumor model C3H/HeJ mice.

The pulmonary artery catheter (PAC) guides diagnosis and treatment in the intensive care unit (ICU), but studies have shown that physicians and nurses collectively have inadequate skill in interpreting PAC waveforms. We have developed a Web-based application that provides physicians and nurses with rapid access to relevant PAC-related content for use in patient care situations in real time. The application begins with a visual index that assists in the recognition of both normal and abnormal waveforms and provides waveform-specific links to concise advice on making accurate pressure measurements, troubleshooting system problems, and avoiding complications of catheter use.

The encoding of clinical practice guidelines into machine operable representations poses numerous challenges and will require considerable human intervention for the foreseeable future. To assist and potentially speed up this process, we have developed an incremental approach to guideline encoding which begins with the annotation of the original guideline text using markup techniques. A modular and flexible sequence of subtasks results in increasingly inter-operable representations while maintaining the connections to all prior source representations and supporting knowledge.
