Purpose: The purpose of this study was to analyse the outcome of vitrectomy for rhegmatogenous retinal detachment without intraoperative use of heavy perfluorocarbon liquids (PFCL).
Material And Methods: All patients who had undergone vitrectomy with a PFCL-free approach during 4/2001-3/2008 by one single surgeon were recruited retrospectively from the electronic database and their data analysed.
Results: A total of 79 patients (42 pseudophakic, 37 phakic) with unilateral surgery were included in the study. The median follow-up was 20.5 months (minimum 3, maximum 133). Median preoperative best-corrected visual acuity was 0.5 logMAR (minimum 0, maximum 2.5) as compared to a postoperative median of 0.45 logMAR (minimum - 0.2, maximum 1.3). The primary anatomic success rate (portion of patients not requiring further retinal surgery, including macular pucker or macular hole surgery) was 70 % for the phakic group, 71 % for the pseudophakic group, and 71 % for all cases. The redetachment rate was 19 % for all cases. The final reattachment rate was 100 %. Complications requiring a repeat surgical intervention occurred in 23 cases, including 7 patients (9 %) with proliferative vitreoretinopathy, and 4 patients (5 %) with macular pucker and macular hole each.
Conclusion: Even though this surgical procedure avoids possible disadvantages of retained intraocular PFCL and may be more cost-effective, the potential benefits do not outweigh the reduced primary anatomic success rate. The authors therefore recommend this approach in selected cases only.

This study evaluated the role of temperature and fine particulate matter in hospitalizations of children living in Cuiabá-MT, obtained from DATASUS, between 01/01/2016 and 12/31/2018. Daily concentrations of the pollutant fine particulate matter were estimated using the CAMS mathematical model, made available by CPTEC. Diagnoses of tracheitis and laryngitis, pneumonia, bronchitis, bronchiolitis and asthma were included.

Purpose: to characterize mastication and electrical activation of the masseter and anterior temporalis muscles in children and adolescents with osteogenesis imperfecta (OI), and relate results to guided occlusion and occlusal interference.
Methods: This observational, analytical cross-sectional study included 22 subjects divided into mild OI (MOI) (type 1) (n=15) and moderate-to-severe OI (MSOI) (types 3, 4, and 5) (n=7) groups. The Orofacial Myofunctional Evaluation with Scores (OMES) form was used to evaluate the clinical aspects of mastication.
Covariate-adjusted construction of gene regulatory networks using a combination of generalized linear model and penalized maximum likelihood.

Many machine learning techniques have been used to construct gene regulatory networks (GRNs) through precision matrix that considers conditional independence among genes, and finally produces sparse version of GRNs. This construction can be improved using the auxiliary information like gene expression profile of the related species or gene markers. To reach out this goal, we apply a generalized linear model (GLM) in first step and later a penalized maximum likelihood to construct the gene regulatory network using Glasso technique for the residuals of a multi-level multivariate GLM among the gene expressions of one species as a multi-levels response variable and the gene expression of related species as a multivariate covariates.

Aim: To construct a predictive model based on the LODDS stage established for patients with late-onset colon adenocarcinoma to enhance survival stratification.
Methods: Late-onset colon adenocarcinoma data were obtained from the public database. After determining the optimal LODDS truncation value for the training set via X-tile software, we created a new staging system by integrating the T stage and M stage.

It is a major challenge to obtain broadband microwave absorption (MA) properties using low dielectric or magnetic nanoparticle-decorated carbon composites due to the limited single conductive loss or polarization loss of the carbon materials used as substrates. Novel pure cellulose-derived graphite carbon (CGC) materials can be used as an exceptional substrate option due to their special defective graphitic carbon structure, which provides both conduction and polarization loss. Herein, CGC@ZnO composites were first synthesized by atomic layer deposition (ALD) for use as microwave absorbents.
