To investigate optic nerve head (ONH) microvascular changes secondary to transsynaptic retrograde degeneration (TRD), comperatively with direct retrograde degeneration and healthy controls. Patients with hemianopia due to intracranial lesion included in the study. Intracranial lesion was categorized by location postgeniculate (causing TRD), chiasmal (causing direct retrograde degeneration). For the postgeniculate lesions, the eye on the same side of the lesion was defined as the ipsilateral eye and the eye on the opposite side as the contralateral eye. Optic disc microvasculature was evaluated with the help of optic coherence tomography angiography. Sixteen eyes of 16 patients with chiasmal lesion, 28 eyes of 14 patients with postgeniculate lesion, and 30 eyes of 30 healthy subjects were included in the study. Ipsilateral eyes of the patients with postgeniculate lesion had decreased vessel density at the temporal sectors compatible with the affected nasal side of the visual field. Contralateral eyes showed no reduction of the vessel density at the affected nasal sectors. The eyes with chiasmal lesions had decreased vessel density at the peripapillary region and nasal half of the ONH compatible with temporal hemianopia. Vascular changes in the chiasmal lesion were more prominent than those of the postgeniculate lesion. Retinal nerve fiber layer and ganglion cell complex thickness were reduced. Vessel density of ONH was reduced in patients with homonymous hemianopia, providing evidence for TRD secondary to acquired postgeniculate lesion. Direct retrograde degeneration was more prominent in affected sectors when compared to TRD.Vessel density of ONH was reduced in patients with homonymous hemianopia, providing evidence for TRD secondary to acquired postgeniculate lesion.

Prospective, nonrandomized, open-label, not-controlled, and single center study conducted on OAG patients who underwent glaucoma surgery with the XEN63 gel stent. The main outcome measure was intraocular pressure (IOP). Secondary end-points were number of topical ocular hypotensive drugs, percentage of patients achieving an IOP reduction ⩾20%, and treatment-related adverse events. Eleven eyes from 11 patients were treated with XEN 63. Mean (95% confidence interval, CI) age was 78.8 (73.7-85.9). Two eyes (18.2%) underwent XEN alone, while nine eyes (81.8%) underwent combined XEN + cataract extraction (phacoemulsification). The median (95% CI) IOP reduction was 17.7% (-13.3% to 34.9%). At the end of the study 9 (81.8%) eyes had an IOP ⩽ 18 mm Hg, six of them without treatment. Six (54.6%) eyes obtained an IOP reduction ⩾20%. Compared to baseline, there was a significant reduction in the number of ocular hypotensive drugs (  = 0.0039). There were no treatment-related serious adverse events. Early postoperative complications included diplopia (1), blood in endothelium (2), ocular hypertension (1), corneal edema (1), folds in Descemet's membrane (1), and contact between the implant and the iris (1). All the adverse events were successfully solved without sequalae. One eye required bleb needling. The XEN63 implant significantly reduced both IOP and the amount of ocular hypotensive medications while maintaining a good safety profile.The XEN63 implant significantly reduced both IOP and the amount of ocular hypotensive medications while maintaining a good safety profile.The elimination of microbial surface contaminants is one of the most important steps in Good Manufacturing Practices in order to maintain food safety. This is usually achieved by detergents and chemical sanitizers, although an increased demand exists for the use of natural products for disinfection purposes. Several natural substances present antibacterial activity against the main foodborne pathogens, demonstrating great potential for use in the food industry. selleck Some difficulties such as high volatility, residual taste and/or degradation by exposure to harsh processing conditions have been reported. Nanoparticle encapsulation appears as a strategy to protect bioactive compounds, maintaining their antimicrobial activity and providing controlled release as well. This article presents the potential of natural antimicrobials and their combination with nanotechnological strategies as an alternative for food surface disinfection and prevent microbial biofilm formation. To assess the use and reporting of risk of bias (RoB) tools in systematic reviews (SRs) of acupuncture. We extracted and analyzed information relating to RoB in acupuncture SRs via Medline, Embase and the Chinese CNKI (Chinese National Knowledge Infrastructure), WanFang and VIP databases from their inception to 24 November 2017. Three subgroup analyses were used to check the influence of language, journal type and impact factor, following which we used descriptive analysis. We included 825 acupuncture SRs, of which 48% used the Cochrane RoB tool. Only 36% used the latest version of the Cochrane Handbook (version 5.1.0 at time of writing) with higher proportions among Cochrane SRs (65%) versus non-Cochrane SRs (34%), and high impact factor journals (58%) versus low or no impact factor journals (28% and 38%, respectively). In the last decade, there were notable increases in the use of the Cochrane RoB tool and Cochrane Handbook version 5.1.0, of 43% and 19%, respectively. Chinese-language SRs demonstrated proportionally higher tendencies to report an incorrect Cochrane Handbook version, increasing by 14% in the last 5 years. Additionally, 7% SRs did not report any results, and only 10% reported relatively complete and adequate RoB assessment. Cochrane SRs reported more complete assessments than Chinese-language or non-Cochrane English-language SRs. Use and reporting of RoB tools were suboptimal. Proportionally, use of the Cochrane RoB tool and Cochrane Handbook version 5.1.0 was low but rising. Our results highlight the prevalence and concerns of using unsuitable tools and the issue of incomplete RoB reporting. RoB tool application requires further improvement.Use and reporting of RoB tools were suboptimal. Proportionally, use of the Cochrane RoB tool and Cochrane Handbook version 5.1.0 was low but rising.
