Cranial repair after traumatic brain injury in children is still burdened by unsolved problems and controversial issues, mainly due to the high rate of resorption of autologous bone as well as the absence of valid alternative material to replace the autologous bone. Indeed, inert biomaterials are associated to satisfactory results in the short period but bear the continuous risk of complications related to the lack of osteointegration capacity. Biomimetic materials claiming osteoconductive properties that could balance their mechanical limits seem to allow good cranial bone reconstruction...

Most phylogenetic models assume that the evolutionary process is stationary and reversible. In addition to being biologically improbable, these assumptions also impair inference by generating models under which the likelihood does not depend on the position of the root. Consequently, the root of the tree cannot be inferred as part of the analysis. Yet identifying the root position is a key component of phylogenetic inference because it provides a point of reference for polarising ancestor/descendant relationships and therefore interpreting the tree...

Osteoporotic vertebral compression fractures (OVCFs) are a significant cause of morbidity and mortality in the United States and worldwide, with estimates of 750,000 to 1.5 million occurring annually. As the elderly population continues to increase, the incidence of OVCFs will continue to rise, as will the morbidity and mortality associated with this condition. Vertebral augmentation (VA) was almost universally accepted as the appropriate treatment modality prior to 2 sham trials published in 2009 by the New England Journal of Medicine (NEJM)...

BACKGROUND: LGR5 serves as a co-receptor for Wnt/β-catenin signalling and marks normal intestinal stem cells; however, its role in colorectal cancer (CRC) remains controversial. LGR5(+) cells are known to exist outside the stem cell niche during CRC progression, and the requirement for epidermal growth factor (EGF) signalling within early adenomas remains to be fully elucidated. METHODS: Epidermal growth factor and gefitinib treatments were performed in EGF-responsive LGR5(+) early adenoma RG/C2 cells...

Nursing Home Compare (NHC) publishes composite quality ratings of nursing homes based on a five-star rating system, a system that has been subject to controversy about its validity. Using in-depth interviews, we assess the views of nursing home administrators and staff on NHC and unearth strategies used to improve ratings. Respondents revealed conflicting goals and strategies. Although nursing home managers monitor the ratings and expend effort to improve scores, competing goals of revenue maximization and avoidance of litigation often overshadow desire to score well on NHC...

To date, the exact impact of mast cells in tumor microenvironment is still controversial because of inconsistency in observations regarding the relationship between mast cell infiltrates and cancer development and prognosis. The discrepancies in previous studies have motivated us to examine the roles of mast cells in cancer pathology from different perspectives. Here, we investigated the impact of mast cells on transcriptomic profiles in the tissue microenvironment. Mice carrying the W-sh mutation in c-kit (Kit(W-sh) ) are deficient in mast cell production and were used to assess the influence of mast cells on gene expression...

Zika virus was recognised in 2016 as an important vector-borne cause of congenital malformations and Guillain-Barré syndrome, during a major epidemic in Latin America, centred in Northeastern Brazil. The WHO and Pan American Health Organisation (PAHO), with partner agencies, initiated a coordinated global response including public health intervention and urgent scientific research, as well as ethical analysis as a vital element of policy design. In this paper, we summarise the major ethical issues raised during the Zika epidemic, highlighting the PAHO ethics guidance and the role of ethics in emergency responses, before turning to ethical issues that are yet to be resolved...

BACKGROUND: Deep brain stimulation (DBS) has been applied in treatment-resistant depression (TRD) as a putative intervention targeting different brain regions. However, the antidepressant effects of DBS for TRD in recent clinical trials remain controversial. METHODS: We searched Scopus, EMBASE, the Cochrane Library, PubMed, and PsycINFO for all published studies investigating the efficacy of DBS in TRD up to Feb 2017. Hamilton depression rating scale (HDRS) scores and Montgomery-Asberg depression rating scale (MARDS) scores were compared between baseline levels and those after DBS using the standardized mean difference (SMD) with 95% confidence intervals (CIs)...
