On the Loewner problem in the class N-kappa
No full textLoewner's theorem on boundary interpolation of N-K functions is proved under rather general conditions. In particular, the hypothesis of Alpay and Rovnyak (1999) that the function f, which is to be extended to an N-K function, is defined and continuously differentiable on a nonempty open subset of the real line, is replaced by the hypothesis that the set on which f is defined contains an accumulation point at which f satisfies some kind of differentiability condition. The proof of the theorem in this note uses the representation of N-K functions in terms of selfadjoint relations in Pontryagin spaces and the extension theory of symmetric relations in Pontryagin spaces
A Hörmander–Fock space
No full textIn a recent paper, we used a basic decomposition property of poly analytic functions of order 2 in one complex variable to characterize solutions of the classical partial derivative(-)-problem for given analytic and polyanalytic data. Our approach suggested the study of a special reproducing kernel Hilbert space that we call the Hormander-Fock space that will be further investigated in this paper. The main properties of this space are encoded in a specific moment sequence denoted by eta= (eta(n))(n= 0) leading to a special entire function E(z) that is used to express the kernel function of the Hormander-Fock space. We present also an example of a special function belonging to the class Mittag-Leffler (ML) introduced recently by Alpay et al. and apply a Bochner-Minlos type theorem to this function, thus motivating further connections with the theory of stochastic processes

The Fueter Mittag-Leffler Bargmann transform
No full textIn this paper we continue exploring the Mittag-Leffler Bargmann (MLB) transform, which maps the Hilbert space L2(R) onto the Mittag-Leffler-Fock (MLF) space. The MLF space is a reproducing kernel Hilbert space that extends the classic Fock space and its reproducing kernel is given by the Mittag-Leffler function. We study the MLB transform and its main properties in the quaternionic setting. In this noncommutative setting there are two function theories that are prominent: the slice hyperholomorphic theory and the Fueter regular theory. The connection between the slice hyperholomorphic functions and the Fueter regular functions is given by the Fueter mapping theorem. The Mittag-Leffler Bargmann transform investigated in this paper maps the quaternionic-valued L2(R, H) space onto a counterpart of the MLF space in the Fueter regular setting. Finally the creation, annihilation, backward-shift and integration operators are studied in the case of the Fueter-MLF space. (c) 2025 The Authors. Published by Elsevier Inc.

Transition of peritoneal dialysis patients from pediatric to adult nephrology unit
No full textDiyaliz tedavisi ve böbrek naklindeki gelişmeler sonucunda, son dönem böbrek yetmezliğinde olan daha fazla sayıda çocuk hasta erişkin döneme ulaşmaktadır. Böbrek nakli kısa dönemde mümkün değilse, periton diyaliz tedavisi genellikle hem sağlık personelinin hem de ailenin tercihi olmaktadır. Genç hastalar için aile merkezli ve koruyucu yaklaşıma sahip çocuk kliniklerinden kendi sorumluluğunu almasını bekleyen erişkin kliniklerine devir (transition) zor olabilir. Bu geçişin hastanın yaşına ve gelişimine uygun olması, tıbbi ve psikolojik gereksinimlerini karşılaması gerekir. Geçiş işlemi hasta dışında ailesini, çocuk doktorunu, erişkin doktorunu, hemşireleri ve sosyal bakım uzmanlarını da içermelidir. Bu işlem özel geçiş polikliniklerinde yapılmalı, bu polikliniklerde hasta izleyen çocuk nefroloji doktoru tarafından tıbbi özeti ile erişkin nefroloji doktoruna sunulmalı ve genç hasta erişkin doktoru ile tanıştırılmalıdır. Periton diyaliz tedavisi almakta olan adolesan hastalar için yapılan uygun ve başarılı devir işlemi, genç hastanın gelecekteki tedavisini ve hastalığının prognozunu olumlu etkileyecektir.Advances in renal transplantation and dialysis have dramatically improved the prognosis of children with end stage renal disease (ESRD) and have allowed most of them to survive to adulthood. If renal transplantation is not possible in the near future, peritoneal dialysis (PD) is the treatment modality of choice for most children with ESRD. It is difficult for young patients to transfer from child-centered and family focussed pediatric services to adult-orientated healthcare units with expectations on patient in terms of responsibility about their illness. The transition process should include patients, families, pediatricians, adult healthcare providers, nurses and social workers and it should not only be appropriate to age, developmental stage but also intellectual ability, psychological and medical needs of the patient. To promote the successful transition of young people, it should be through a transition clinic where the young patient is seen by pediatric and adult specialists before being transferred. An appropriate and successful transition of adolescents performing PD will have a positive effect on the future treatment and prognosis of the illness
Cefepime-induced non-convulsive status epilepticus n a peritoneal dialysis patient
No full textNon-convulsive status epilepticus related to cefepime has not been reported in childhood dialysis patients, although several adult cases have been reported. We report a state of acute confusion in a 15-year-old boy on continuous ambulatory peritoneal dialysis (CAPD) receiving cefepime that was diagnosed as status epilepticus by electroencephalography (EEG). The EEG improved after anticonvulsive therapy. All clinical symptoms disappeared dramatically within 24 h of discontinuation of cefepime. The differential diagnosis of confusional states and the mechanisms of the convulsive effects of antimicrobials in chronic renal failure are discussed. The importance that the clinician is aware of the rare side effects of antimicrobials is emphasized. © IPNA 2004
