XEN 63 gel stent device in glaucoma surgery: A 5-years follow-up prospective study.

Eur J Ophthalmol 2021 Jul 18;31(4):1829-1835. Epub 2020 Aug 18.

Ophthalmology Department, University Hospital La Paz, Madrid, Spain.

Purpose: To evaluate the efficacy and safety of the XEN63 Gel Stent in patients with open-angle glaucoma (OAG).

Methods: 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.

Results: 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.

Conclusion: The XEN63 implant significantly reduced both IOP and the amount of ocular hypotensive medications while maintaining a good safety profile.

Excess mortality in Italy: Should we care about low influenza vaccine uptake?

Scand J Public Health 2018 Mar 24;46(2):170-174. Epub 2017 Oct 24.

2 Department of Medicine and Surgery, University of Parma, Italy.

Aims: The aims of this study were to explore 2015 mortality data further and to assess excess deaths' determinants.

Methods: We analysed data from a large metropolitan area in the north of Italy, the city of Bologna. We took advantage of a comprehensive local-level database and merged three different data sources to analitically explore reported 2014-2015 excess mortality and its determinants. Effect estimates were derived from multivariable Poisson regression analysis, according to vaccination status and frailty index.

Results: We report 9.8% excess mortality in 2015 compared to 2014, with seasonal and age distribution patterns in line with national figures. All-cause mortality in the elderly population is 36% higher (risk ratio [RR]=1.36, 95% confidence interval [CI] 1.27-1.45) in subjects not vaccinated against seasonal flu compared to vaccinated subjects, with risk of death for influenza or pneumonia being 43% higher (RR=1.43, 95% CI 1.02-2.00) in unvaccinated subjects.

Conclusions: Reported excess mortality's determinants in Italy should be further explored. Elderly subjects not vaccinated against the flu appear to have increased risk of all-cause and cause-specific mortality compared to vaccinated subjects after accounting for possible confounders. Our findings raise awareness of the need to promote immunisation against the flu among elder populations and offer insights to plan and implement effective public-health interventions.

[Device availability to successful applications--a definition of terms].

Authors:
R Schwarck O Anna

Biomed Tech (Berl) 1994 Nov;39(11):287-92

The operation of technical equipment is increasingly considered an important part of quality. But the terms related with "operation" are seldom clearly used. A terminology is hardly ever seen. Nevertheless, a generally accepted and uniformly used definition of terms is essential for scientific work. In this paper, the path from the availability of a device to the successful application is inquired. The terms used are defined. The central term "operation" is examined for significance and requirements. The differences between the man and the machine aspects are stressed. The wish to optimize operation leads to the psychological factors, their significance and a survey of the potential for further optimization of operation using biomedical devices as an example.

["No-touch" measurement of skin temperature in cerebral ischemia and lesions of the sympathetic trunk. Clinical and technical testing of a new infrared apparatus for measuring skin temperature (Ultrakust Thermophil M 202) (author's transl)].

MMW Munch Med Wochenschr 1977 Nov;119(45):1463-6

The clinical test was carried out in extracranial carotid occlusions and acute peripheral paralysis with sympathetic lesions. The measurements obtained were compared with those of the infrared thermovision. Both in the technical and in the clinical tests, the device proved to be very suitable. The practical procedure of temperature measurement (cerebral ischemia and lesions of the sympathetic trunk) is described.
