EDITORIAL
Jason Chertoff
Recent studies have shown acute respiratory distress syndrome (ARDS) to be underdiagnosed and inadequately treated, as evidenced by underutilization of low-tidal volume ventilation. Despite a proven survival benefit in patients with severe ARDS, studies have also shown underutilization of prone positioning. Many questions persist as to the reasons for prone positioning's unpopularity. Additional studies are required to uncover the causes of this prone positioning underutilization phenomenon.

Quality of motivation, self-control competencies, as well as past performance experience influence sport participation outcomes in developing athletes. Studies have shown that junior athletes high in self-determined motivation are less prone to experience burnout, while self-control competencies help developing athletes to be conscious and deliberate in their self-regulatory efforts toward elite sport performances and avoid negative sport participation outcomes. Combining the self-determination theory framework and psychosocial theories of self-regulation, the aim of this cross-sectional study was to examine how various types of motivation and self-control competencies together are associated with the development of burnout symptoms in junior athletes...

Preventing intraoperatively acquired pressure ulcers (IAPUs) in patients undergoing spinal surgery in the prone position using a Relton-Hall frame is challenging. We investigated the efficacy of soft silicone foam dressings in preventing IAPUs. A prospective dual-center sham study was conducted among patients undergoing elective spinal surgery in a general hospital and a university hospital in Japan. The incidence of IAPUs that developed when soft silicone foam dressings and polyurethane film dressings were used was compared on two sides in the same patient...

CpG islands (CGI) marked by bivalent chromatin in stem cells are believed to be more prone to aberrant DNA methylation in tumor cells. The robustness and genome-wide extent of this instructive program in different cancer types remain to be determined. To address this issue we developed a user-friendly approach to integrate the stem cell chromatin signature in customized DNA methylation analyses. We used publicly available ChIP-sequencing datasets of several human embryonic stem cell (hESC) lines to determine the extent of bivalent chromatin genome-wide...

Acute respiratory distress syndrome occupies a great deal of attention in intensive care units. Despite ample knowledge of the physiopathology of this syndrome, the focus in intensive care units consists mostly of life-supporting treatment and avoidance of the side effects of invasive treatments. Although great advances in mechanical ventilation have occurred in the past 20 years, with a significant impact on mortality, the incidence continues to be high. Patients with acute respiratory distress syndrome, especially the most severe cases, often present with refractory hypoxemia due to shunt, which can require additional treatments beyond mechanical ventilation, among which is mechanical ventilation in the prone position...

Anterior cervical osteophytes are commonly found in elderly patients, but rarely produce symptoms. When symptoms occur, they can range from mild symptoms of dysphagia, dysphonia, and foreign body sensation to severe symptoms of airway obstruction due to compression of the pharynx or larynx. We report the case of a 59-year-old man who underwent brain tumor surgery, and developed post-operative respiratory difficulty due to progressive pharyngo-laryngeal edema, requiring urgent endotracheal intubation, secondary to the presence of a previously asymptomatic anterior cervical osteophyte...

PURPOSE OF REVIEW: Timely recognition of acute respiratory distress syndrome (ARDS) may allow for more prompt management and less exacerbation of lung injury. However, the absence of a diagnostic test for ARDS means that the diagnosis of ARDS requires clinician recognition in what is usually a complicated and evolving illness. We review data concerning the extent of recognition of ARDS in the era of the Berlin definition of ARDS. RECENT FINDINGS: ARDS continues to be under-recognized - even in the era of the more recent 'Berlin' definition, and significant delay in its recognition is common...

OBJECTIVE: Skull base chordomas are clinically malignant because of the difficulty of total removal and the high recurrence rate. Because the disease-free survival after surgery is currently unpredictable, there is a need for new parameters obtained from histological analyses of the resection specimen that allows a risk stratification of patients with chordoma. METHODS: Electron microscopic diagnoses were introduced into the clinical practice for the diagnosis of chordoma in our department in recent years...

Even with the revolution of gene-targeting technologies led by CRISPR-Cas9, genetic modification of human pluripotent stem cells (hPSCs) is still time consuming. Comparative studies that use recombinant lines with transgenes integrated into safe harbor loci could benefit from approaches that use site-specific targeted recombinases, like Cre or FLPe, which are more rapid and less prone to off-target effects. Such methods have been described, although they do not significantly outperform gene targeting in most aspects...

Horizontal gene transfer (HGT) among flowering plant mitochondria occurs frequently and, in most cases, leads to nonfunctional transgenes in the recipient genome. Parasitic plants are particularly prone to this phenomenon, but their mitochondrial genomes (mtDNA) have been largely unexplored. We undertook a large-scale mitochondrial genomic study of the holoparasitic plant Lophophytum mirabile (Balanophoraceae). Comprehensive phylogenetic analyses were performed to address the frequency, origin, and impact of HGT...

Characterization of phosphorus (P) pools is vital to understanding the contribution of P to water eutrophication. In this study, dissolved and particulate P classes during an algae bloom in Lake Taihu, as well as their relationships with the main environmental factors, were analyzed based on solution (31)P NMR. The results showed that dissolved P was dominated by orthophosphate (Ortho-P) in heavily polluted regions and by orthophosphate monoester (Mono-P) and orthophosphate diester (Diester-P) in lightly polluted regions, indicating that the main dissolved P classes varied with the degree of lake pollution...

There is considerable controversy regarding the association between smoking and prognosis in surgically treated bladder cancer. The present meta-analysis was performed to quantify the role of smoking status in bladder cancer recurrence, progression and patient survival by pooling the available previous data. Pubmed, Embase and the Cochrane Library databases were searched for eligible studies published prior to April 2016. Random and fixed effects models were used to calculate the summary relative risk estimates (SRRE)...

BACKGROUND: Legionella species cause 5% of all community acquired pneumonias. However, Legionella pneumonia results relatively often in admission to the intensive care unit (ICU). A significant complication is the development of acute respiratory distress syndrome (ARDS). The ICU mortality rate for Legionella pneumonia is > 30% with conventional treatments. CASE DESCRIPTION: A 64-year-old male was admitted to the ICU with respiratory failure due to Legionella pneumonia complicated by ARDS...

BACKGROUND: It is very important to assess the effectiveness of prone positioning (PP) in patients with severe acute respiratory distress syndrome (ARDS). However, it is difficult to identify patients who may benefit from PP. The purpose of this study was to investigate whether prone positioning potential (PPP) can be predicted by lung ultrasound in patients with ARDS. METHODS: In this prospective study, 45 patients with ARDS were included for the assessment of PPP...

Dispositional shame and guilt have been associated with psychopathology and an increasing number of studies have traced this relation back to adolescence. This developmental period is thought to be characterized by maturational changes in emotion regulation, which also play an important role in vulnerability to psychopathology, but little is known about the links between emotion regulation and dispositional shame and guilt. The current study investigated the relations between individual differences in the habitual use of a wide range of emotion regulation strategies and proneness to shame and guilt in a large sample of adolescents (N = 706), aged 13 to 17 years...

PURPOSE OF REVIEW: Critically ill patients with acute respiratory distress syndrome (ARDS) may require sedation in their clinical care. The goals of sedation in ARDS patients are to improve patient comfort and tolerance of supportive and therapeutic measures without contributing to adverse outcomes. This review discusses the current evidence for sedation management in patients with ARDS. RECENT FINDINGS: Deep sedation strategies should be avoided in the care of patients with ARDS because deep sedation has been associated with increased time on mechanical ventilation, longer ICU and hospital length of stay, and higher mortality in critically ill patients...

PURPOSE OF REVIEW: Severe respiratory failure due to the acute respiratory distress syndrome (ARDS) might require rescue therapy measures beyond even extended standard care to ensure adequate oxygenation and survival. This review provides a summary and assessment of treatment options that can be beneficial when the standard approach fails. RECENT FINDINGS: 'Life-threatening' conditions or refractory hypoxemia during mechanical ventilation are more a matter of personal rating than an objective diagnosis based on defined and/or unanimously agreed thresholds that would mandate the use of rescue therapies...
