To compare the outcomes between 2 groups of patients with complete clefts treated with early secondary alveolar bone grafting (ABG) at 2 centers (5-7 years,

orthodontic intervention) and to a third group of patients treated at one of those centers (center 1) who had received later secondary ABG (8-10 years,

orthodontic intervention).

Blind retrospective analysis of cleft site radiographs using Americleft Standardized Way to Assess Grafts (SWAG) scale.

A total of 99 patients with complete clefts from 2 North American cleft/craniofacial centers.

Secondary ABG representing 2 protocols early grafting at a mean age of 6.6 years prior to any orthodontic intervention, and later grafting at a mean age of 10.2 years following pregrafting orthodontic intervention.

Using occlusal radiographs, the SWAG scale from 0 (failed graft) to 6 (ideal) was used. Six trained, calibrated raters scored each radiograph twice, with the average of the 2 ratings used as the final score. Bay 11-7083 Reliability was assessed using the weighted κ statistic. The significance of differences between groups was determined using the Kruskal-Wallis test and Dunn test for pairwise comparisons.

Inter-rater reliability of SWAG method was good (0.631). Intra-rater reliability was excellent (0.817). There was a tendency for improved total graft outcome in the early grafted group from center 1 compared to the later grafted group with improvement being significantly different in only the coronal third of the early, preorthodontic grafted group. However, the difference was not statistically significant for the graft overall.

Methods Serum relative expressions of the specified long non-coding RNAs were quantified in 155 consecutive women, using quantitative reverse-transcription PCR. Random Forest (RF) and decision tree were also applied. Results Significant MALAT1 upregulation and GAS5 downregulation could discriminate risky women from healthy controls. Overexpression of the other genes showed good diagnostic performances. Lower GAS5 levels were associated with metastasis and recurrence. RF model revealed a better performance when combining gene expression patterns with risk factors. Conclusion The studied panel could be utilized as diagnostic/prognostic biomarkers in BC, providing promising epigenetic-based therapeutic targets.

This study aimed to determine the correlations between the craniofacial morphology and pharyngeal airway volume in patients with complete bilateral cleft lip and palate (BCLP).

Retrospective study.

Tertiary hospital.

Twenty-seven patients with complete BCLP and 27 class I control patients, aged 10 to 14 years.

The pharyngeal airway volume and craniofacial morphology were evaluated using cone-beam computed tomography. Measurements were compared between groups and any correlations were identified.

A significantly smaller total pharyngeal airway volume (TPV), oropharyngeal airway volume, and upper (UOPV) and lower (LOPV) oropharyngeal airway volume were found in patients with BCLP than in class I control patients, with no difference in the nasopharyngeal volume between groups. Furthermore, the craniofacial morphology measurements of N-Me, S-Go, Or-C, Ptm-C, Me-C, Co-Go, Go-Me, Ptm-Or, N-S-Ar, and Ar-Go-Me significantly differed between the BCLP and control groups (all

< .05). Multiple regression analysis indicated that Ptm-C and Me-C; Ptm-C, Or-C, and Me-C; and Me-C explained 20.3%, 38.9%, and 17.1% of the variations in TPV (

= .025), UOPV (

= .002), and LOPV (

= .018), respectively.

Total pharyngeal airway volume, TPV, OPV, UOPV, and LOPV were significantly smaller in patients with BCLP than in class I controls. In patients with BCLP, the maxilla showed inhibited sagittal development and a retrograde position; moreover, the pharyngeal airway volume was weakly associated with the position of the maxilla and mandible relative to the coronal plane.

The goal of this study was to identify ICU metrics meaningful to stakeholders to help guide the development of a local visualization dashboard. Individual ICU directors were interviewed to collate their input on metrics important to their units. These qualitative data were used to develop a dashboard draft, after which the authors surveyed 20 stakeholders from different hospital departments for feedback on its content and structure. The varied survey results reinforced the inherent difficulties of adapting previously developed measurement tools while also selecting ICU performance measures that are simultaneously widely accepted yet relevant to local practice. These results also call attention to the importance of interdisciplinary input in quality dashboard development, thereby enabling more successful implementation and utilization for ICU quality improvement.We report 8-year experience with vascular access complications (VACs) after percutaneous transfemoral transcatheter aortic valve implantation (TAVI). From January 2010 to January 2018, patients with iliofemoral VAC treated by an intervention following percutaneous transfemoral TAVI were included. Major VAC was defined according to the Valve Academic Research Consortium 2 classification. As first-line strategy, VACs were treated using covered nitinol stents (CS). Among 795 percutaneous transfemoral TAVI, 74 (9.3%) patients (female, 57%; 82 ± 8 years) with VAC treated by CS and/or open repair were included in this study 59 CS cases and 15 open repair cases. Two CS patients were converted to open repair. Technical success for stent implantation was 97%. The main VAC was a persistent bleeding related to percutaneous closure device failure (72%). Thirty-day mortality in the study cohort was 5.4% (4/74), including 1 VAC-related death. One patient had postoperative lower limb ischemia successfully treated by open repair. No amputation, new-onset claudication or in-stent occlusion was recorded. Endovascular intervention using self-expandable nitinol covered stent is safe and effective as a first-line strategy for the treatment of VAC in percutaneous transfemoral TAVI. However, open repair is needed in case of unfeasibility or failure of endovascular therapy.Small open reading frame encoded proteins (SEPs) gained increasing interest during the last few years because of their broad range of important functions in both prokaryotes and eukaryotes. In bacteria, signaling, virulence, and regulation of enzyme activities have been associated with SEPs. Nonetheless, the number of SEPs detected in large-scale proteome studies is often low as classical methods are biased toward the identification of larger proteins. Here, we present a workflow that allows enhanced identification of small proteins compared to traditional protocols. For this aim, the steps of small protein enrichment, proteolytic digest, and database search were reviewed and adjusted to the special requirement of SEPs. Enrichment by the use of small-pore-sized solid-phase material increased the number of identified SEPs by a factor of 2, and utilization of alternative proteases to trypsin reduced the spectral counts for larger proteins. The application of the optimized protocol allowed the detection of 210 already annotated proteins up to 100 amino acids (aa) length, including 16 proteins below 51 aa in the Gram-positive model organism Bacillus subtilis. Moreover, 12% of all identified proteins were up to 100 aa, which is a significantly larger fraction than that reported in studies involving traditional proteomics workflows. Finally, the application of an integrated proteogenomics search database and extensive subsequent validation resulted in the confident identification of three novel, not yet annotated, SEPs, which are 21, 26, and 42 aa long.The transition-metal-catalyzed direct carboxylation of an unactivated C-H bond is rarely reported, and no example of catalysis using abundant and cheap nickel has been reported. In this work, the first Ni-catalyzed direct carboxylation of an unactivated C-H bond under an atmospheric pressure of CO2 is reported. This method affords moderate to high carboxylation yields of various methyl carboxylates under mild conditions. Preliminary mechanistic studies reveal that a Ni(0)-Ni(II)-Ni(I) catalytic cycle may be involved in this reaction.The transition-metal-promoted C-H activation has become an efficient as well as atom-economic methodology for the synthesis of a wide array of organic molecules, but the cost of the metal catalyst and selectivity remain the major challenges. Herein, the first [Cl2Ru(p-cymene)]2-catalyzed direct monoarylation of unactivated C(sp3)-H bonds of 8-methyl quinolines with arylboronic acids to synthesize diarylmethane compounds is presented. The transformation shows a broad substrate scope with high chemoselectivity for the synthesis of 8-benzyl quinolines. In the preliminary mechanistic studies, control experiments, deuterium labeling experiments, and kinetic studies have been performed.An iridium-catalyzed selenium-directed ortho-C-H borylation of benzyl selenide derivatives was successfully developed. This is the first example where selenium is used as a directing group in C-H borylation. The reaction was carried out using the tricyclohexylphosphine ligand for an improved catalytic efficiency. Various substrates were tolerated and afforded either ortho-monoborylated products (substrates bearing ortho- or meta-substituents) or diborylated products (substrates bearing para-substituents) in good yields. This study provides an efficient synthetic method for the preparation of a variety of organoselenium compounds.We report the ruthenium-catalyzed cyclization of 1,6-diynes with two molecules of carbon monoxide and water to give a variety of catechols. This reaction likely proceeds through the intermediacy of the water-gas shift reaction to generate an yne-diol-type intermediate followed by a [4 + 2] cycloaddition with 1,6-diynes. The reaction requires no external reductants or hydride sources and provides a novel and valuable method for the synthesis of a variety of catechols.
