Subjective photic phenomena with refractive multifocal and monofocal intraocular lenses. results of a multicenter questionnaire.
2001
Abstract Purpose To compare the incidence and severity of photic phenomena after the implantation of the Array® (Allergan) refractive multifocal intraocular lens (MIOL) and a monofocal IOL. Setting Multicenter study at Kiel, Mainz, Karlsruhe, and Bremerhaven, Germany. Methods The study comprised 231 randomly selected patients from 4 study centers. The patients had had uneventful phacoemulsification with implantation of a refractive MIOL (n = 138) or a monofocal IOL (n = 93). By questionnaire, patients were asked whether they experienced light sensations postoperatively (light streaks, halos, flare, flashes, or glare) that had not been noticed preoperatively. Additional questions evaluated w…
Body size at birth and age-related macular degeneration in old age
2019
Purpose To study associations between body size at birth and age-related macular degeneration (AMD) in old age. Methods The study sample consists of 1497 community-dwelling individuals (56.1% women) aged 67-89 years with birth data and retinal data collected twice in old age 5 years apart. Birth data (weight, length, birth order) were extracted from original birth records. Digital retinal photographs were graded to determine AMD status. Data on covariates were collected at the baseline physical examination in old age. Multivariable regression analyses were used to study the association between birth data and AMD adjusting for known confounding factors, including birth year cohort effects. R…
Dysfunctional High-Density Lipoproteins Are Associated With a Greater Incidence of Acute Coronary Syndrome in a Population at High Cardiovascular Risk
2020
Background: Studies have failed to establish a clear link between high-density lipoprotein (HDL) cholesterol and cardiovascular disease, leading to the hypothesis that the atheroprotective role of HDL lies in its biological activity rather than in its cholesterol content. However, to date, the association between HDL functional characteristics and acute coronary syndrome has not been investigated comprehensively. Methods: We conducted a case-control study nested within the PREDIMED (Prevención con Dieta Mediterránea) cohort, originally a randomized trial in which participants followed a Mediterranean or low-fat diet. Incident acute coronary syndrome cases (N=167) were individually matched …
Coincidence and common fixed points of weakly reciprocally continuous and compatible hybrid mappings via an implicit relation and an application
2015
Using the hybrid version of the notion of weakly reciprocal continuous mappings due to Gairola et al. [Coincidence and fixed point for weakly reciprocally continuous single-valued and multi-valued maps, Demonstratio Math. (2013/2014), accepted], we prove a coincidence and common fixed point theorem for a hybrid pair of compatible mappings via an implicit relation. Our main result improves and generalizes a host of previously known theorems. As an application, we give a homotopy theorem which supports our main result.
A Series of Hadamard Designs with Large Automorphism Groups
2000
Abstract Whilst studying a certain symmetric (99, 49, 24)-design acted upon by a Frobenius group of order 21, it became clear that the design would be a member of an infinite series of symmetric (2q2 + 1, q2, (q2 − 1)/2)-designs for odd prime powers q. In this note, we present the definition of the series and give some information about the automorphism groups of its members.
INCIDENCE OF PSYCHOTIC DISORDERS IN PALERMO: PRELIMINARY DATA
2012
Background: The incidence of psychotic disorders varies in different geographical areas (McGrath 2004). Recent data suggest that the incidence is higher in males, migrant minorities and in urban areas. There aren’t many available epidemiological data on the incidence of psychotic disorders in Italy. This is the first incidence study on psychotic disorders carried out in Palermo, the capital of Sicily. Methods: we screened all patients presenting with their first episode of psychosis to the mental health services of our catchment area (5 inpatient, 5 outpatient units and 3 private psychiatric hospitals) over a period of three years (2008-2011). The diagnosis of psychosis was defined using th…

Kaulu cementa implantācijas sindroms pacientiem ar gūžas artroplastiju
2019
Kaulu cementa implantācijas sindroms (KCIS) ir viens no nozīmīgākiem intraoperatīvas mirstības cēloņiem, pēc literatūras datiem ir ap 0,11%, un ir galvenokārt asociēts ar gūžas artroplastiju. Sindroma patoģenēze nav līdz galam skaidra, un sindroma skaidra definīcija un gradācija tika ieviesta 2009. gadā. Kopš definīcijas ieviešanas, tika veikts viens epidemioloģisks pētījums, un pēc tā datiem pirmās pakāpes KCIS incidence ir 21%, otrās pakāpes incidence ir 5,1% un trešās pakāpes – 1,7%. Mērķis bija izanalizēt KCIS incidenci pacientu grupām ar dažādām gūžas hemiartroplastijas tipiem un identificēt iespējamus riska faktorus. Pētījums ir retrospektīvs, un tika veikts Traumatoloģijas un ortopēd…
Incidence and Management of Recurrence in Patients with Crohn's Disease Who Have Undergone Intestinal Resection: The Practicrohn Study.
2017
Background: More than 50% of patients with Crohn's disease require intestinal resection at least once. Postoperative recurrence (POR) is almost uniform if prophylactic treatment is not started early. Endoscopic monitoring is generally advised. We studied the incidence and management of recurrence in patients who had undergone intestinal resection. Methods: Practicrohn was an observational retrospective study performed in 26 Spanish hospitals including patients aged >= 18 years who underwent Crohn's disease-related ileocolonic resection between January 2007 and December 2010. We recorded preventive treatments, the incidence of clinical recurrence in daily practice, and associated risk factor…
Wymuszenie rozbójnicze i rozbiór - analiza znamion czynów zabronionych na tle statystyk sądowych
2018
Artykuł poddaje analizie kontrowersyjne zagadnienie różnic występujących pomiędzy przestępstwem wymuszenia rozbójniczego a rozbojem. W rozważaniach odniesiono się do doktryny oraz orzecznictwa wskazując na liczne wątpliwości pojawiające się w tej materii. Podjęto również próbę wyznaczenia granic jakie dzielą te przestępstwa. W części drugiej odniesiono się do statystyk sądowych obrazujących dynamikę czynu zabronionego wymuszenia rozbójniczego. W szczególności zaprezentowano dane dotyczące liczby przestępstw wszczętych oraz stwierdzonych porównując je również z przestępstwem rozboju. Wskazano nadto liczbę prawomocnych przestępstw z art. 282 k.k. z uwzględnieniem płci oraz wieku sprawców.
